Introduction
Thank you for purchasing and using the Chameleon AntennaTM Tactical Dipole Lite Version 2
(CHA TD LITE V2) antenna. The CHA TD LITE V2, shown in plate (1), is a broadband High
Frequency (HF) antenna specially designed for use in short to long range portable and base
station HF communication where rugged and dependable operation is essential. The CHA TD
LITE V2 is the result of experience gained from over six years of daily on-the-air base station
usage of the original CHA TD Lite. The CHA TD LITE V2 is an excellent choice for a permanent
base station antenna, due to its’ rugged design and ability to operate on all ham bands from
160 –6m, using your rig’s built-in antenna tuner. The CHA TD LITE V2 will operate from 1.8 - 54
MHz without any adjustment, making it ideal for military, government agencies, non-
governmental organizations (NGOs), Military Affiliate Radio System (MARS), Civil Air
Patrol (CAP), Amateur Radio Emergency
Service (ARES) / Radio Amateur Civil
Emergency Service (RACES), Salvation Army
Team Emergency Radio Network (SATERN),
and amateur radio operators (hams)
involved in field communication. The CHA
TD LITE V2 is configurable to facilitate Near-
Vertical Incident Sky wave (NVIS)
communication and its broadband design
supports Automatic Link Establishment
(ALE), frequency-hopping, and spread-
spectrum modes when used with an
automatic antenna tuner. The CHA TD LITE
V2 can be deployed by the operator in the
field in less than 15 minutes, using almost
any available support, with no masts or
guying required.

manual so that you may maximize the
utility you obtain from your CHA TD LITE V2.
HF Propagation
HF radio provides relatively inexpensive and reliable local, regional, national, and international
voice and data communication capability. It is especially suitable for undeveloped areas where
normal telecommunications are not available, too costly or scarce, or where the commercial
telecommunications infrastructure has been damaged by a natural disaster or military conflict.

CHA TD LITE V2 Page 4
Although HF radio is a reasonably reliable method of communication, HF radio waves propagate
through a complex and constantly changing environment and are affected by weather, terrain,
latitude, time of day, season, and the 11-year solar cycle. A detailed explanation of the theory
of HF radio wave propagation is beyond the scope of this operator’s manual, but an
understanding of the basic principles will help the operator decide what frequency and which of
the CHA TD LITE V2’s configurations will support their communication requirements.
HF radio waves propagate from the transmitting antenna to the receiving antenna using two
methods: ground waves and sky waves.
Ground waves are composed of direct
waves and surface waves. Direct waves
travel directly from the transmitting
antenna to the receiving antenna when
they are within the radio line-of-sight.
Typically, this distance is 8 to 14 miles for
field stations. Surface waves follow the
curvature of the Earth beyond the radio
horizon. They are usable, during the day
and under optimal conditions, up to around
90 miles, see table (1). Low power,
horizontal antenna polarization, rugged or
urban terrain, dense foliage, or dry soil
conditions can reduce the range very
significantly. The U.S. Army found that in
the dense jungles of Vietnam, the range for
ground waves was sometimes less than one
mile.

Table 1. Maximum Surface Wave Range by
Frequency.
Sky waves are the primary method of HF radio wave propagation. HF radio waves on a
frequency below the critical frequency (found by an ionosonde) are reflected off one of the
layers of the ionosphere and back to Earth between 300 and 2,500 miles, depending upon the
frequency and ionospheric conditions. HF radio waves can then be reflected from the Earth to
the ionosphere again during multi-hop propagation for longer range communication. The most
important thing for the operator to understand about HF radio wave propagation is the concept
of Maximum Usable Frequency (MUF), Lowest Usable Frequency (LUF), and Optimal Working
Frequency (OWF). The MUF is the frequency for which successful communications between
two points is predicted on 50% of the days of in a month. The LUF is the frequency below
which successful communications are lost due to ionospheric loses. The OWF, which is
somewhere between the LUF and around 80% of the MUF, is the range of frequencies which
can be used for reliable communication. If the LUF is above the MUF, HF sky wave propagation
is unlikely to occur.
The HF part of the Radio Frequency (RF) spectrum is usually filled with communications activity
and an experienced operator can often determine where the MUF is, and with less certainty,
the LUF by listening to where activity ends. The operator can then pick a frequency in the OWF

CHA TD LITE V2 Page 5
and attempt to establish contact. Another method is using HF propagation prediction
software, such as the Voice of America Coverage Analysis Program (VOACAP), which is available
at no cost to download or use online at www.voacap.com.The operator enters the location of
the two stations and the program shows a wheel with the predicted percentage of success
based on frequency and time. ALE, which is the standard for interoperable HF communications,
is an automated method of finding a frequency in the OWF and establishing and maintaining a
communications link.
Even under optimal conditions, there is a gap between where ground waves end (around 40 to
90 miles) and the sky wave returns to Earth on the first hop (around 300 miles). NVIS
propagation can be used to fill this gap. The frequency selected must be below the critical
frequency, so NVIS can normally only be used on frequencies from around 2 to 10 MHz.
Frequencies of 2 –4 MHz are typical at night and 4 –8 MHz during the day.

Antenna Configurations
Using the supplied components, the CHA TD LITE V2 can be configured as various kinds of wire
antennas. Four of the most operationally useful configurations are described in this manual,
each with unique performance characteristics, see table (2). The table can assist the operator
to quickly select the most appropriate antenna configuration to meet their operational
requirements.

Table 2. Antenna Configuration Selection.
To use the table, decide which distance column (Ground = 0 to 90 miles, Short = 0 - 300 miles,
Medium = 300 –1500 miles, Long > 1500 miles) best matches the distance to the station with
whom you need to communicate. Then, determine if the OWF is in the lower (↓ = 1.8 – 10
MHz) or upper (↑ = 10 – 30 MHz) frequency range. Finally, select the CHA TD LITE V2
configuration with the corresponding symbol in the appropriate distance column. All CHA TD
LITE V2 configurations provide some capability in each distance category, so depending upon
the complexity of your communications network, you may need to select the best overall
configuration. The directionality column indicates the directionality characteristics of the
antenna configuration. The directionality characteristics are highly dependent on antenna
height and frequency and when using NVIS, all the configurations are omnidirectional. Most
configurations and frequency combinations will require an antenna tuner.

CHA TD LITE V2 Page 8
Inverted “V”
The CHA TD LITE V2 Inverted “V” configuration, see figure (1), is a broadband medium to long
range HF antenna. It provides good medium range sky wave propagation on all frequencies and
long range sky wave propagation on 14 MHz and above. When mounted at a height of around
25 feet, the Inverted “V” will provide good overall performance and on lower frequencies,
tends to be bidirectional broadside to the antenna. The Inverted “V” is the most often used
configuration as it is fast and easy to deploy because it requires only a single support and
provides good performance.
Figure 1. Inverted “V” Configuration.
Site Selection and Preparation.
1. Select a site to deploy the CHA TD LITE
V2 Inverted “V”configuration. The best
site should have a tree or other support
that would enable the Matching
Transformer to be at a height of around
25 feet. If a tall support is unavailable,
any convenient object, such as a fence
post or the top of a vehicle, may be
used as a field expedient support with
reduced performance.
2. Connect a Carabiner (I) to the Insulator
Loops (H) at the Wire Connector (G)
ends of the Antenna Wires (F).
Connect the Matching Transformer. Refer
to plate (2) for steps (3) –(8).
3. Connect the Carabiner from one of the
Antenna Wires to the Transformer
Eyebolt (B).
4. Connect the Wire Connector from the
Antenna Wire to the Bottom Antenna
Connection (D). Tighten the wing nut
finger tight.

CHA TD LITE V2 Page 9
5. Connect the Carabiner from the other
Antenna Wire to the Transformer
Eyebolt.
Plate 2. Matching Transformer Electrical
and Mechanical Connections.
6. Connect the Wire Connector from the
Antenna Wire to the Top Antenna
Connection (C). Tighten the wing nut
finger tight.
7. Using a Bowline or similar knot, tie one
end of a long length (around 50 feet) of
Paracord to the Transformer Eyebolt.
8. Connect the UHF Plug from the Coaxial
Cable to the UHF Socket (E) on the
Matching Transformer.
Raise the antenna.
9. Using a throw weight or some other
method, loop the long length of
Paracord over the support.
10. Raise the antenna to the desired height
and secure the Paracord to the support
with a Round Turn and two Half Hitches,
or similar knot.
Extend the Antenna Wires to make an
Inverted “V”.
11. Using a Bowline of similar knot, tie a
short length of Paracord (around 4 feet)
to the Insulator Loops (H) at the
unconnected ends of both Antenna
Wires.
12. Extend one Antenna Wire to its full
length.
13. Drive a Stake in the ground around two
feet beyond the end of the Antenna
Wire.
14. Using two Half Hitches, tie the short
length of Paracord from the Antenna
Wire to the Stake, such that the
Antenna Wire is not quite taut.
15. Extend the other Antenna Wire to its
full length in the opposite direction
from the other Antenna Wire.
16. Drive a Stake into the ground around
two feet beyond the end of the Antenna
Wire.
17. Tie the Paracord from the Antenna Wire
to the Stake, such that the Antenna
Wire is not quite taut.
18. Perform operational test.

CHA TD LITE V2 Page 10
Horizontal Dipole
The CHA TD LITE V2 Horizontal Dipole configuration, see figure (2), is a broadband short to long
range HF antenna. The Horizontal Dipole is the standard for wire HF antennas and will provide
good sky wave (including NVIS) propagation. It requires three supports - one at each end and
one in the middle. The Horizontal Dipole should be mounted at a height of around 25 feet for
good overall performance. When mounted at this height, on lower frequencies the antenna
tends to be bidirectional broadside to the antenna. The pattern becomes a clover leaf at higher
frequencies. NVIS propagation characteristics are enhanced if the antenna is mounted lower
(around 10-15 feet) at the expense of overall performance and the antenna becomes omni-
directional.
Figure 2. Horizontal Dipole Configuration.
Site Selection and Preparation.
1. Select a site to deploy the CHA TD LITE
V2 Horizontal Dipole configuration. A
good site should have two trees or
other supports that are more than 120
feet apart and are tall enough that the
ends of the antenna will be at a height
of around 25 feet. The site must also
have center support for the antenna. If
the right supports are not present, any
convenient objects, such as fence posts
or the tops of vehicles, may be used as
field expedient supports with reduced
performance.
2. Connect a Carabiner (I) to the Insulator
Loops (H) at the Wire Connector (G)
ends of the Antenna Wires (F).
Connect the Matching Transformer. Refer
to plate (2) for steps (3) –(8).
3. Connect the Carabiner from one of the
Antenna Wires to the Transformer
Eyebolt (B).
4. Connect the Wire Connector from the
Antenna Wire to the Bottom Antenna

and secure the Paracord to the support
with a Round Turn and two Half Hitches,
or similar knot.
Extend the Antenna Wires.
11. Fully extend both Antenna Wires in a
straight line in opposite directions along
the ground.

long length (around 50 feet) of Paracord
to the Insulator Loops (H) at the free
ends of the Antenna Wires.
Raise the antenna ends.
13. Using a throw weight or some other
method, loop the Paracord over the end
supports.
14. Raise the ends of the antenna to the
desired height and secure the Paracord
to the supports with a Round Turn and
two Half Hitches, or similar knot.
15. Perform operational test.

CHA TD LITE V2 Page 12
Sloping Wire
The CHA TD LITE V2 Sloping Wire configuration, see figure (3), is a broadband short to medium
range HF antenna. It is designed to provide acceptable ground wave and sky wave propagation,
while also being quick and easy to put up. This configuration is somewhat unidirectional above
10 MHz, becoming more omni-directional on lower frequencies. The Sloping Wire requires one
support, is a good general-purpose antenna, and is excellent for hasty deployment. It should be
mounted at a height of around 25 feet for best performance.
Site Selection and Preparation.
1. Select a site to deploy the CHA TD LITE
V2 Sloping Wire configuration, see
figure (4). The best site should have a
tree or other support that would enable
the end of the antenna to be at a height
of around 25 to 40 feet. If a tall support
is unavailable, any convenient object,
such as a fence post or the top of a
vehicle, may be used as a field
expedient support with reduced
performance.
2. Connect a Carabiner (I) to the Insulator
Loops (H) at the Wire Connector (G)
ends of the Antenna Wires (F).
Connect the Matching Transformer. Refer
to plate (2) for steps (3) –(8).
3. Connect the Carabiner from one of the
Antenna Wires to the Transformer
Eyebolt (B).
4. Connect the Wire Connector from the
Antenna Wire to the Top Antenna
Connection (C). Tighten the wing nut
finger tight.

Wire.
11. Fully extend the Antenna Wire.
12. Drive a Stake around two feet beyond
the low end of the Antenna Wire.
13. Using two Half Hitches, tie the short
length of Paracord from the Matching
Transformer to the Stake, such that the
Antenna Wire is not quite taut.
14. Extend around 25 feet of the
counterpoise Antenna Wire along the
ground in any convenient direction. The
rest of the wire may be left on the Line
Winder.
15. Connect the UHF Plug from the Coaxial
Cable to the UHF Socket (E) on the
Matching Transformer.
16. Perform operational test.

CHA TD LITE V2 Page 14
Inverted “L”
The CHA TD LITE V2 Inverted “L” configuration, see figure (4), is a broadband short to medium
range HF antenna for frequencies below 12 MHz. One of the primary uses for this antenna is
NVIS propagation, however the take-off angle of this antenna below 4 MHz may be good for
nighttime long distance communication. This configuration is somewhat bidirectional, favoring
the ends of the antenna wire. This configuration will provide effective ground waves
communication during the daytime on frequencies between 1.8 –4 MHz without using sky
wave propagation. The Inverted “L” requires two supports and should be mounted at a height
of around 25 feet for best overall performance. It will have increased NVIS characteristics when
mounted at height of 10 to 15 feet, at the expense of overall performance.
Figure 4. Inverted L Configuration.
1. Select a site to deploy the CHA TD LITE
V2 Inverted “L” Wire configuration. The
best site should have two trees or other
support around 35 feet apart that would
also enable the ends of the antenna to
be at a height of around 25 feet (10 –15
feet for NVIS). If tall supports are
unavailable, any convenient objects,
such as fence posts or the tops of
vehicles, may be used as a field
expedient support with reduced
performance.
2. Connect a Carabiner (I) to the Insulator
Loops (H) at the Wire Connector (G)
ends of the Antenna Wires (F).

CHA TD LITE V2 Page 15
Connect the Matching Transformer. Refer
to plate (2) for steps (3) –(8).
3. Connect the Carabiner from one of
Antenna Wires to the Transformer
Eyebolt (B).

Antenna Wire to the Top Antenna
Connection (C). Tighten the wing nut
finger tight.
5. Connect the Carabiner, from the other
Antenna Wire to the Transformer
Eyebolt.
6. Connect the Wire Connector from the
Antenna Wire to the Bottom Antenna
Connection (D). Tighten the wing nut
finger tight. This Antenna Wire becomes
the counterpoise in this configuration.
7. Using a Bowline or similar knot, tie one
end of a short length (around 4 feet) of
Paracord to the Transformer Eyebolt.

8. Drive a Stake next to the first support.
9. Using two Half Hitches, tie the short
length of Paracord from the Matching
Transformer to the Stake.
10. Using a Bowline or similar knot, tie a
long length (around 50 feet) of Paracord
to the Insulator Loop (H) at the free end
of the Antenna Wire connected in step
4.
11. Using another long length of Paracord,
tie a Bowline or similar knot to the
floating Insulator Loop.
12. Using a throw weight or some other
method, loop the long lengths of
Paracord over the supports.
Extend the Antenna Wire and Counterpoise
Wire
13. Extend the Antenna Wire between the
two supports.
14. Raise the floating Insulator Loop and the
end Insulator Loop so the Antenna Wire
is horizontal and at the desired height.
The Antenna Wire from the Matching
Transformer to the floating Insulator
Loop should be vertical. The full length
of the Antenna Wire should form a
sideways “L”, as shown in figure (5).
15. Secure the Paracords to the supports
using a Round Turn and two Half
Hitches or similar knot.
16. Extend around 25 feet of the
counterpoise Antenna Wire along the
ground in any convenient direction. The
rest of the wire may be left on the Line
Winder.
17. Connect the UHF Plug from the Coaxial
Cable to the UHF Socket (E) on the
Matching Transformer.
18. Perform operational test.

Recovery Procedure
To recover the CHA TD LITE V2, perform the following steps:
1. Disconnect the Coaxial Cable from the radio set.
2. Lower the antenna to the ground.
3. Disconnect the Coaxial Cable from the Matching Transformer.
4. Carefully roll (do not twist) the Coaxial Cable.
5. Untie the Paracord from the Matching Transformer and Antenna Wires.
6. Disconnect the Antenna Wires from the Matching Transformer.
7. Wind the Antenna Wires onto their Line Winders and secure with attached shock cord.
8. Pull the Stakes from the ground, if used.
9. Remove dirt from antenna components and inspect them for signs of wear.
10. Store components together to avoid loss and facilitate the next deployment.
Troubleshooting
1. Ensure Wire Connectors are securely connected.
2. Inspect Antenna Wires for breakage or signs of strain.
3. Ensure UHF Plugs are securely tightened.
4. Inspect Coaxial Cable assembly for cuts in insulation or exposed shielding. Replace if
damaged.
5. If still not operational, connect a Standing Wave Ratio (SWR) Power Meter and check SWR.
6. If SWR is close to infinite (∞), check antenna tuner using the technical manual or
manufacturer’s procedure. Be sure to check the Coaxial Patch Cable that connects the radio
set to the antenna tuner.
7. If still not operational, replace Coaxial Cable assembly. Most problems with antenna
systems are caused by the coaxial cables, end connectors, and even adapters.
8. Connect a Multi-Meter to the Antenna Wires to check continuity. Replace assemblies that
do not pass a continuity check.
9. If still not operational, contact Chameleon AntennaTM for technical support.
