Engineering parts will ensure that your Hustler BTV antenna will enable you to achieve an
outstanding presence on the amateur bands for years to come.
Over 50 Years Ago!
The Hustler HF Base Four Band Trap Vertical antenna was a new concept in 1959. This unique multi-
band antenna with an exclusive low-loss trap design was developed and introduced to Amateurs by
Hustler, Inc. of Cleveland, Ohio, offering quarter-wave antenna performance for 40, 20 15 and 10
meters , but requiring no band switching!
Later, the Hustler Four Band Trap Vertical, known around the world as the 4-BTV, was made
available with an 80 meter resonator, and the 5-BTV was born. When the Amateur bands expanded in
1979, the last of the series offerings designed by Hustler, the 6-BTV, added 30 meters, for an
unequalled vertical antenna. Since 1985 the New-Tronics Antenna Corporation in Mineral Wells,
Texas, has been making high quality antennas for HF, VHF and UHF Amateur and Commercial
customers, including the “Hustler BTV Series”.
Since 2003, DX Engineering has offered Hustler Antennas and has developed a complete system of
innovative accessories and Add-On Kits specifically for the Hustler BTV series. Amateurs now have
the choice of complete Hustler BTV Series High Performance packages for their HF needs, including
the ability to turn their Hustler into a “9-BTV” covering all bands 80 through 10 meters.
DX Engineering joins New-Tronics Antenna Corporation in celebrating over 50 years of service with
the famous Hustler HF Base Four Band Trap Vertical – The Hustler 4-BTV.

Hustler BTV Antennas
The Hustler 4-BTV is a four-band trap vertical antenna
providing an omni directional pattern. The 4-BTV is
designed as a self supporting vertical to provide optimum
performance on the 10, 15, 20 and 40 meter bands. This
antenna is designed for installations with restricted space.
The Hustler 4-BTV is approximately 19 feet tall. It can also
be adapted to operate on the 75/80 meter band by adding the
RM-80S resonator and the 4457-1 three blade spider
assembly on top of the 4-BTV. If the 75/80 meter resonator
is attached to the 4-BTV, it may be desirable to guy the
antenna above the 20 meter trap with small diameter
polypropylene rope.
The Hustler 5-BTV is a five-band trap vertical antenna. This
antenna includes the RM-80S resonator and the 4457-1 three
blade spider assembly. The 5-BTV is designed to provide
excellent performance on the 10, 15, 20, 40 and 75/80 meter
bands. The Hustler 5-BTV is approximately 24 feet tall.
The Hustler 6-BTV is a six-band trap vertical antenna. The
6-BTV is designed to provide excellent performance on the
10, 15, 20, 30, 40 and 75/80 meter bands, using four traps
and the RM-80S resonator. The design of the 6-BTV is sleek,
with no capacity spiders and is approximately 25 feet tall.
The Hustler BTV antennas provide automatic electrical
selection of the bands through the use of optimum Q traps,
which are individually and precisely tuned at New-Tronics.
The traps are parallel tuned circuits which provide efficient
isolation between the vertical sections, permitting multi-band
operation. Efficient operation over the many ham bands at
good SWRs is possible in a proper installation.
The Hustler BTV antennas were designed to provide optimum performance from both an electrical
and mechanical standpoint. Mechanically, this antenna boasts a heavy duty base and heavy duty
aluminum tubing. The mechanical assembly is accomplished with all stainless steel hardware. The
use of clamps permits re-adjustment if necessary, and allows tuning of each band. The mechanical
construction is such that guying is not ordinarily needed.
The performance provided by the Hustler BTV antenna is better than any other antenna of this type.
Broad banding is such that one setting permits both phone and CW operation on most bands. The
antenna provides a nominal 52 Ωbase impedance when installed and tuned according to
instructions. The radiation efficiency is equivalent to, or greater than, other trap verticals.

Assembly Notes 7
WARNING!
INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS
Warning:Do not locate the antenna near overhead power lines or other electric light or power
circuits, or where it can come into contact with such circuits. When installing the antenna, take
extreme care not to come into contact with such circuits, because they may cause serious injury or
death.
Overhead Power Line Safety
Before you begin working, check carefully for overhead power lines in the area you will be
working. Don't assume that wires are telephone or cable lines: check with your electric utility for
advice. Although overhead power lines may appear to be insulated, often these coverings are
intended only to protect metal wires from weather conditions and may not protect you from electric
shock
Keep your distance! Remember the 10-foot rule: When carrying and using ladders and other long
tools, keep them at least 10 feet away from all overhead lines - including any lines from the power
pole to your home.
Basic Tools Required
Two 7/16" open end wrenches or nut drivers
Medium size flat blade screwdriver or 5/16" nut driver for the element clamps
Tape measure
Felt-tip marker
Assembly Notes
Note: DXE-P8A Penetrox A Anti-Oxidant should be used between all antenna element
sections. Penetrox is an electrical joint compound to affect a substantial electrical
connection between metal parts such as telescoping aluminum tubing or other
antenna pieces. It ensures high conductivity at all voltage levels by displacing moisture
and preventing corrosion or oxidation.
Note: DXE-81343 Never-Seez or NSBT8 Anti-Seize should be used on all clamps, bolts and
stainless steel threaded hardware to prevent galling and to ensure proper tightening.

Site Selection
•Install your new vertical antenna a minimum of 20 feet away from buildings, wires,
metal fences, downspouts and gutters. Centering a vertical antenna in an open area is the
best option. Installing the antenna near a wooden fence or on a wood post is okay as long
as there is no metal within 20 feet of the antenna.
•Installing the antenna on a metal mounting pipe or a wooden post that is set in concrete
is okay. Since the radial system wires create the efficient ground return for RF currents,
direct earth grounding of the support post or a ground rod is not required at the antenna.
Select a mounting location clear from power lines, structures and other antennas by a minimum of
40 feet (30 + 10 ft safety rule). Consider overhead power lines, utility cables and wires. The
further away the vertical is mounted from local noise sources or other metallic objects, which can
re-radiate noise and affect the tuning, radiation pattern and SWR, the better. Determine the direction
you want the antenna to pivot and make sure there is adequate clearance (at least 30 feet).
Mounting Pipe
The mounting support may be a galvanized metal pipe or thick wall steel tube from 1 inch to 1-3/4
inches outside diameter (OD) when using just the Hustler bracket, and 1 inch to 2 inches OD when
using the DXE-TB-3P Tilt Base. A thick-walled steel pipe with a minimum thickness of 1/8" (1/4"
preferred) should be used. The standard 1-1/2" galvanized water
pipe (with its 1.9" OD) is just fine for this application and can
usually be found at your local home building supply store. A 4
to 6 inch wood post can also be used.
Use a thick-walled galvanized steel mounting pipe
approximately 6 feet long. This will allow approximately 4 feet
to be below ground and 20-23 inches above ground.
The height of the mounting pipe above ground level of 20-23
inches will allow you to do either a basic installation, or an
enhanced installation by adding the DX Engineering optional
items described in this detailed manual. In some cases ham
operators have done a basic installation, and then added the DX
Engineering optional items at a later date to enhance their
operation. Thus, the length of mounting pipe above ground is 20
to 23 inches.
For permanent mounting, use a post-hole digger to make the
hole deep enough to accommodate approximately 4 feet of pipe
and a couple inches of gravel at the bottom for drainage. Set the
pipe on the gravel, use the pre-mix concrete to fill around the
pipe, adding water and mixing as you fill (or mix the concrete
first, depending on the type you purchase), then pour the
concrete in the hole. Fill the hole until the concrete is level with the ground around it. Use a level as
you fill the hole to be sure the pipe is vertically straight. Allow to set overnight.

- 10 -
Your location, landscape and ground conditions may require different mounting solutions in order
to have the steel mounting pipe and the vertical antenna in a secure position. You may also attach
the Tilt Base to a 4 to 6 inch wooden post at the location you intend to use the antenna, making sure
the unit is securely mounted.
Using a cyclone fence is not recommended for a vertical antenna support or being used as a radial
system. Poor RF connections and the presence of high levels of noise that are inherent on metal
fences make them an undesirable mounting location for any HF vertical antenna.
Note: Steel, rather than aluminum, is much more suitable for mounting in concrete. Aluminum
will quickly corrode due to incompatibility with the materials used to make concrete.
Concrete or No Concrete – That is THE Question
The original Hustler BTV installation manuals call for the ground mounting pipe to be driven into
the earth with the specific wording “Do not use concrete. Do not dig a hole and bury the mast. It
must be driven in.” The reason for this recommendation is so that installations with few or no
radials will be able to make use of the direct contact between the mounting pipe and the earth to
collect and distribute antenna currents.
Unfortunately, the soil and a steel pipe usually does not provide efficient RF conduction. Therefore,
the use of many ground radial wires are recommended for all quarter-wave ground mounted HF
antenna, to improve efficiency and performance dramatically.
Also, a driven or pounded pipe may be used on any ground-mounted vertical antenna installation,
regardless of the number of radials used.
DX Engineering recommends using a concrete base, as shown on page 9, when a high performance
installation with many radials is planned. The reasons that a concrete base is recommended:
1. It is easier to make sure that the mounting pipe is vertical when it is braced for installation
with concrete. Pounded pipes can develop a lean or hit a rock while being driven into the
ground, which could result in a leaning antenna.
2. A steel pipe or tube in concrete will last much longer than in soil, especially in certain types
of soil that will corrode steel more quickly.
3. Concrete is not an insulator for a steel pipe, as the hardened but moist concrete is a good
conductor from the steel to the soil for grounding purposes.
4. A ground surface wire radial system offers far more efficient means to collect and distribute
surface RF currents than a single pipe in the soil, so a pipe in concrete is okay when using
many radials.

- 11 -
Coaxial Cable to Mounting Pipe
The coaxial cable should be routed from your radio room to the base
of the antenna system and be buried below the radial system you will
be installing.
PVC Conduit pipe may be used to house the coaxial cable. Bury the
cable 4" to 12" below ground level.

Get the Best Performance From Your New Quarter-Wave Vertical Antenna
To be certain to get optimum performance from this vertical design, please assemble and install
your new antenna according to these DX Engineering Assembly and High Performance
Installation Instructions. These instructions are intended to replace those originally supplied by
the manufacturer. The Hustler BTV series of antennas is manufactured by New-Tronics Antenna
Corporation, Mineral Wells, Texas.
By following these instructions you will be able to take advantage of all of the performance that
your Hustler HF Multi-Band Vertical has to offer. Here are a few facts about the HF quarter-wave
vertical antenna:
•For best results, plan for a ground-mount installation with many radials. Engineers and
Amateurs “in-the-know” install a complete ground radial wire system to significantly
improve quarter-wave vertical antenna performance for transmitting and receiving. Use
copper wire. Do not use grids, mesh fence material or steel which are known to be poor
performers especially for the long term.
•Mounting this antenna without radials results in average to below average performance and
only local or medium range contacts. Due to RF ground losses, a vertical installation with no
radials or only a few radials will have drastically reduced efficiency. On those installations,
even though a wider frequency range of low SWR may result, that is a very poor trade-off
for an antenna system that offers performance.

- 12 -
•Any HF vertical mounted a few to many feet above ground with only a few radials suffers
virtually the same ground losses as a ground mounted vertical with a few radials. This
manual shows you how to plan and install ground radials for better antenna performance and
gratifying operational results in almost any situation.
•Height is not a requirement for HF Verticals. Unlike horizontally oriented antennas, ground
mounted vertical antennas used for HF sky wave communications only require a radial
system for performance. If an HF quarter-wave vertical antenna is elevated, then it requires
resonant, quarter wavelength, tuned radials to be efficient and functional. Safer ground-
mounted installations can produce results far superior to elevated HF verticals with a few
radials.
•For low-angle performance, a horizontal antenna requires height, and if it is directional, may
not be able to be rotated, or it requires a tower and rotator. In comparison, an omni-
directional HF vertical installed with many radials offers an excellent performance-to-cost
value.
Some Brief Words on Ground Mounting, Elevated Mounting, and Radial Wires
Ground Mounting
There are multiple ways to install a Hustler BTV antenna. The most efficient way is to ground
mount the antenna, keeping clear of any metal objects and using a good ground radial system.
Ground mounting your quarter-wave vertical antenna will produce significantly improved long
range results when your installation includes a good ground-level radial wire system. Seven decades
of experiments show that ground mounting with many radials is your best choice.
Safety is another important consideration when comparing ground mounting to
roof-top or elevated mounting of your quarter-wave vertical. The DX
Engineering Tilt Base offers a safer and easier ground mounted installation.
One person can walk-up and tilt-down the antenna for adjustments without a
ladder. The new, more versatile Tilt Base models are also helpful when high
winds are expected. Order the Tilt Base model DXE-TB-3P for your Hustler
BTV.
Elevated Mounting
You may also elevate the Hustler BTV antenna. However, when elevating the antenna the radial
system becomes more difficult to deploy in that you need specific length radials that must also be
elevated, running symmetrically away from the feedpoint.
In some situations, an elevated or roof-mounted vertical installation is the only option. Resonance-
tuned radials must do the job of collecting RF currents. Imagine all of the quarter-wave resonant
length wires attached to the base of the antenna, spreading radially (away from the base of the
vertical in all directions). For best DX performance, these radials should slope down from the
elevate vertical at a 45 degree angle. You can connect the ends of the long radials to support poles
or trees. Use the same care as you would for a dipole antenna, keeping the ends insulated and clear

- 13 -
of any metal. We recommend four resonant radials per band to enhance low angle radiation. More
information on planning and installing the elevated quarter-wave vertical appears later in Chapter 9.
Radial Wires
Radials: Probably THE most important item, for not only the Hustler BTV, but any ground
mounted quarter-wave vertical antenna system are the radial wires. Lack of radial wires causes a
serious compromise to performance.
Will the antenna work without radial wires? In most cases, yes - BUT - it will work at a much lower
efficiency in both transmit and receive. Some hams who tried the 'no radial' method and later added
a good radial system were very surprised in the difference it made with enhanced transmit
efficiency and the ability to receive many more weak signals. The importance of a good radial
system cannot be stressed enough.
Radials are easy to install and the following section outlines the easiest and most efficient way of
installing radial wires that will withstand a powered grass mower and provide your antenna with the
best possible radial system.
How To Put Radial Wires Down Without Digging
The best time to do this is early spring but it can be done other times, as well. I have even done it in
the fall and had good success.
The idea behind this is to get the grass of your lawn to grow over the radials and protect them from
the mower.
First, mow the grass pretty short in the areas where you will be laying the radials down. Notice, I
didn't say "scalp" it. Just lower the mower until the grass is about 1 inch long after cutting. Readjust
the height of the mower back to normal and put it away.
Next, connect the radials to the Radial Plate with wire terminal
ends (which you can get at DX Engineering along with the
radial wire) and stretch them out while arraying them evenly
around the antenna. Some AM broadcast engineers tell us that
the radials should be as long as you can make them up to about
1/2 wavelength. If you can only do 1/4 wave or 1/8 wave in
certain directions then do that and don’t worry about it. You
will be surprised how much better your vertical will work.
After you install 20 to 40 radials and see how much better your
antenna performs you will have an urge to put in more of them.
Don’t resist. More really is better.
Starting from the antenna end of the radials, and about every 3-4 feet, hold the wire down with a
Steel or Biodegradable Radial Wire Anchor Pin while pulling the radial out from the antenna to
keep it taut. Push it in as far as possible to get the wire as close to the grass roots as possible. I

- 14 -
typically use a rubber mallet to drive it home. If the radial
wire is sticking up any place due to uneven ground or the
wire is loose just put another staple there. The idea is to get
all parts of the wire down as close as possible to the ground
so that the grass can grow over it.
When you finish the last radial, your job is done. Mother
Nature will do the rest. If you have done this in the early
spring, the grass will grow up, surround the wire and pull it
down firmly along its full length. If you do it in the fall after
the grass has stopped growing, it will happen the next
spring. This will be done so completely that in a few weeks you will have to actively look for the
radials to see them.
Your mower will miss them completely, too; but you and your contacts will hear them right away!

Note: Radial Wires shown above have Red insulation so they would show up in the
photographs. DX Engineering Radial Wire has a relaxed Black PVC insulation.
Radial System Considerations
The performance of any quarter-wave vertical antenna, multi-band or single band, is completely
dependent upon the quality of its radial system. A few local or medium range contacts may be
possible using a minimal installation without radials. However, you will get more consistent results
and much better performance with a complete radial system. The radial system required depends on
whether it is for a ground-mounted or a roof-mounted vertical and on the number of radials you can
install.
Many amateurs enjoy excellent quarter-wave vertical performance with only 20 to 30 radials. On
ground-mounted quarter-wave verticals, the length of the radial wires is not
critical. They can be as short as one-eighth wavelength, but one-quarter
wavelength radials on the lowest band of operation are typical. Long lasting
and high-efficiency radial wire connections are easy to make using the
stainless steel DX Engineering DXE-RADP-3 Radial Plate. Use the radial
plate for a simple and neat way to install as many ground radial wires as you
wish. Install 30 to 60 radials for higher performance using one or more DX
Engineering radial wire kits. The relaxed black PVC insulated 14 gauge
stranded copper wire in our Radial Wire Kits is easy to handle and will last far longer than bare wire
or wire mesh.
Why is such an extensive array of radial wires necessary? Simply put, it is the best way to increase
your signal! The entire radial system must collect and carry currents equal to those flowing in the

- 15 -
vertical section of the antenna. The ground-mounted vertical antenna needs many radial wires to
prevent your RF power from being absorbed by the "lossy" ground. Even if your radials cannot run
in all directions, you still get improved
signals and prevent ground losses by
installing as many symmetrically
spaced radials as you can. You may
use wires of any convenient length.
Just run your radials in as many
directions as you can, straight away
from the antenna base taking care not
to zig-zag, bunch or cross over other
radial wires. Radial by definition run in all directions,
NOT parallel, NOT zig-zags, NOT crossing over each
other. Run your radial wires in a spoke pattern.
Install your coaxial cable under the radials, at least a few
inches in the ground, to minimize coupling between the
radials and the coaxial cable shield. Additional
decoupling the feedline can be effectively accomplished
using a DX Engineering current choke instead of coiled
coaxial cable, to reduce RF feedback, RFI.
•To avoid damage from radial installation and for proper RF decoupling, the coaxial cable
should be buried several inches under the radial system.
•Performance of the antenna is directly proportional to the
number and length of radials. Many short radials are better
than a few long radials. The stainless steel DX Engineering
DXE-RADP-3 Radial Plate makes it easy to attach long-
lasting radial wire connections.
•You don’t have to dig! Radial wires disappear under the grass
when installed with DX Engineering steel or biodegradable
anchor pins.
•DO NOT bother to cut ground radials to resonant lengths because they are detuned by the
ground. It is best to install many radials that are all the same length or lengths that fill a
small irregular space.
•Radial wires should run in all directions straight from the base feedpoint of the antenna.
Ground radials cannot be bunched together for any length. If your radials cannot cover 360
degrees, that is okay. The antenna performs nearly the same with an equal number of radials
squeezed into directions that cover smaller arcs.
Plan to install at least 20 radials using DX Engineering Radial Wire Kits. However, improved
performance is accomplished using 30 to 60 radial wires.

Assembling Vertical Aluminum Antenna Sections & Element Clamps
Note: DXE-P8A -Penetrox A Anti-Oxidant should be used between all antenna element
sections. Penetrox is an electrical joint compound to affect a substantial electrical
connection between metal parts such as telescoping aluminum tubing or other antenna
pieces. It ensures high conductivity at all voltage levels by displacing moisture and
preventing corrosion or oxidation
When assembling any telescoping aluminum tubing sections you should take the following steps:
1. Make sure the edges are smooth and not sharp. Deburring may be necessary, since burrs and
shavings can occur on seams as well as edges. All surfaces need to be completely smooth to
allow easy assembly of tubing sections.
Caution
Aluminum tubing edges can be very sharp.
Take precautions to ensure you do not get accidentally cut.
The raised particles and shavings that appear when the aluminum tubing is machined are
referred to as burrs, and the process by which they are removed is known as deburring.
Deburring is a finishing method used in manufacturing. Aluminum tubing is machine cut on
both ends and machine slit as needed. Although Hustler manufactured aluminum tubing is
deburred, you should further assure that there are no ragged edges or protrusions.
Use the DXE-22166 Slim Grip Deburring Tool, or the DXE-22600 Deburring Tool with
Extending Handle and Extra Blades for this operation.
2. Clean the inside of the aluminum tubing to clear out any dirt or foreign material that would
cause the aluminum tubing sections to bind during assembly. Do not use any type of oil or
general lubricant between the aluminum tubing sections. Oils or general lubricants can cause
poor electrical connections for radio frequencies.

3. Clean the outside of the aluminum tubing to clear any dirt or foreign material that would cause
the clamps to malfunction during assembly.
4. The use of DXE-P8A Penetrox A is highly recommended. Penetrox A is an electrical joint
compound which effects a substantial electrical connection between metal parts such as
telescoping aluminum tubing or other antenna pieces. Using Penetrox A assures high
conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.
5. When assembling the aluminum tubing sections, ensure the area is clear of grass, dirt or other
foreign material that could cause problems during assembly of the closely fitted telescoping
sections.
Assemble the vertical sections in an area that is flat and has sufficient room for the length of the
antenna during assembly.
Assembly is easier if the tubing sections are pre-marked. A dark color felt-tip marker works well.
Locate the hardware pack containing the element clamps.
Refer to the following 4-BTV, 5-BTV or 6-BTV assembly instructions, depending on your antenna,
for element clamps, tubing and trap placement.
Slide all the clamps over each section before putting them together. You can lightly
tighten the clamps just below the slits in each section to hold them until needed.
Align the clamp screws on each section to face the same direction.
At final assembly, body of the clamp should be positioned between the slits in the
tubes and 1/8" from the edge of each tube as shown to the right.
Making sure dirt or grass does not adhere to the sections to be joined. The body of the
element clamp is positioned between the slits and tighten securely.
The following charts show the suggested starting measurements for the 4/5-BTV and 6-BTV
antennas. Note the charts show different measurements for various installation methods.
