Please read and follow these important safety precautions:
•
Be sure to select an antenna site well away from all overhead wires.
• Do not try to guess which overhead wires carry high voltage.
Check with the Power Company.
• If you notice anything making contact with the overhead wires,
call the Power Company to have it removed safely. Do not run
the downlead cable over power wires.
• Get help from a qualified professional when removing the old
antenna if there is any doubt of clearing overhead wires.
• Never install the antenna outdoors at night, when it is windy, or
during rain or snow.
• Make sure the antenna installation is secure.
• Do not stand on, lean on, hang from or hang anything on the
antenna once it is mounted.
Lightning Protection and Grounding
Always plug your radio and other electronics devices into a quality
surge protector for maximum protection against lightning and
power surges.
• Do not run the downlead cable over power wires.
• Make sure the antenna downlead is connected to suitable
lightning arrestors.
All outdoor antenna installations should be properly grounded. To
effectively protect the installation, the coaxial cable(s) should be
grounded before they enter the house. The grounding of
the coaxial cable is made using a “ground block” and copper
wire (not supplied). For information and the materials
needed to ground your antenna installation, visit your local
electronics store.

Safety Precautions
Warning!
Use extreme caution when installing or removing an outdoor
antenna that is located close to overhead wires such as power
lines, telephone lines or cable TV lines. If any part of the antenna
makes contact with overhead power lines, touching the antenna
or the antenna cable can cause electrocution and death. If the
antenna is in contact with any type of overhead wires, call your
power company and ask them to send a qualified technician to
remove the antenna. Do not attempt to remove it yourself!
Important Safety Precautions...
Many do-it-yourself and professional antenna installers are
injured or killed each year by electric shock. While anyone can see
the obvious danger of falling, the most resourceful sometimes fail
to recognize overhead wires as being potentially lethal. To touch
any part of the antenna to these overhead wires is the same as
touching the wires with your bare hand. A very serious shock is
almost sure to result when contacting an electrical wire, and in
the case of primary wires on the top of poles, the shock is like
being struck by a bolt of lightning. Many power wires are within
20 to 25 feet of the ground and could easily be touched by an
assembled antenna.

About Your New TERK
HDRo Antenna and HD Radio
HD Radio (digital AM/FM transmission) is revolutionizing the
way people experience radio. It provides the best of traditional-
transmission radio (it's free and over-the-air), with the best of digital,
CD-quality sound. The performance of HD Radio is noticeably better
than regular radio—no more buzzing, static or channel overlap,
just the clear music, sports, talk and news you want in your home.
Stations broadcasting in HD will also be providing more content, with
multiple broadcast channels in their frequency band, so you’ll get
more from the stations you already love.
Terk has been the leader in antenna technology for more than 20
years and has been making HD Radio capable antennas since its
inception. To maximize your enjoyment of the HD Radio content
available, you need an antenna that’s designed and engineered
for better performance. Terk’s line of HD Radio antennas offers
consumers the best in design, style and engineering to receive
these crystal clear digital signals. Terk's high-gain, ultra-low-
noise amplified antennas will ensure you get the best possible
reception. Terk HD Radio Antennas also significantly enhance the
performance of the traditional analog broadcast.
Your Terk HDRo antenna is designed for both single and
multifamily homes. The HDRo’s unique antenna technology
produces the clearest and cleanest signals available, from a
compact, unobtrusive design that blends well with any home décor.

Positioning the HDRo
The HDRo must be mounted so that it has a clear line of sight to the
radio broadcaster’s towers (see Fig. 3). The higher the elevation of
the antenna, the better the reception performance will be.
Please note that the HDRo antenna is an omni-directional antenna
and can receive signals from any direction. However, you can also
fine tune the antenna to your favorite station after mounting.
The HDRo can be mounted to a wall or soffit using the 4 lag bolts
to mount the mounting bracket. The HDRo can also be mounted to
a standard antenna mast using the supplied u-bolts, u-bolt clamp
brackets and wing nuts.
Once mounted the antenna can be rotated on it’s mounting
bracket if needed. To fine tune the HDRo once mounted:
1. Use the included hex key (Allen wrench) to loosen the set screw
on the antenna housing where indicated by an arrow.
2. Lift the antenna up off the internal indexing cup. Be careful not
to lose the set screw.
3. Rotate the antenna as needed to fine tune your reception. The
indexing cup allows you to rotate the antenna in 10 degree
increments.
4. Lower the antenna back on to the indexing cup and lock in
place with the set screw (see Fig. 2).

Mounting the HDRo Antenna
Mounting Options:
For Best performance, the HDRo should be mounted outdoors
in a high location (such as a roof). It can also be mounted on a
standard antenna mast (not included), which can be mounted to
the side of your house or a chimney. You can also mount the HDRo
in your attic. However, mounting the antenna inside the attic can
degrade the performance of the antenna.

The HDRo can be mounted:
- with the bracket and 4 included lag bolts to a flat surface
OR
- with the bracket and 2 included u-bolts, clamps and 4 wing nuts
to a mast (not included)
NOTE: Do not install the HDRo on any metal surface, including
aluminum siding. Mounting on a metal surface will seriously
degrade reception quality.
WARNING: Never hang anything from the HDRo or attach foreign
objects to the HDRo.
NOTE: When using a mast to mount the HDRo, it is recommended
that you first install the mast at the desired location, and then
attach the antenna to the mast.
1. Connect RG6 coaxial cable to the HDRo antenna and run the
cable into the room where your radio is located.
Connect the other end of the coaxial cable to the supplied
Power Injector to the terminal labeled “ANT”. (See fig. 5)
NOTE: Do not plug in the Power Injector yet.
Connecting the HDRo to a Radio
2. The way you connect the Power Injector to your radio depends
on the type of connection your radio offers.
If your radio only has an “F” connector for FM and no
connections for AM:
Connect the coaxial cable from the Power Injector labeled “FM
/ DIPLEXER” directly to the FM input of your radio.

Avoiding Water Damage
Water Damage Prevention:
At the point where your coaxial cable lead enters the house, you
should allow for some slack in the coaxial cable as a “drip loop.”
This will prevent moisture from running down the coaxial cable
and entering the house.
Run the coaxial cable approximately six inches below the wall
entry point and then turn it upwards towards this spot (see Fig 9).
Any moisture that accumulates on the coaxial cable will drip off
in the bend instead of running into the house. You should seal the
point where the cable enters your home with a rubber weather
insulator or silicone caulking (not included). An “F” connector wall
plate can be used inside the home to cover the inside portion of
the hole. You can typically find an “F” connector wall plate at any
local electronics or hardware store.

If your radio has both separate antenna connections for AM
and FM:
Use the included Diplexer to make the connection. Connect the
coaxial cable from the Power Injector labeled “FM / DIPLEXER”
to the supplied Diplexer (Band Separator) to the terminal
labeled “POWER INJECTOR”
Then, connect the coaxial cable from the Diplexer labeled
“FM” to the FM input “F” connector on your radio.Connect the
twin lead wire from the Diplexer labeled “AM” to the AM input
on your radio. Note that the wire with the white stripe is the
positive (+) connection. If your radio’s AM connection is color
coded black and red, connect the wire with the white stripe to
the red connector.
