line in opposite directions along the ground.
11.
Using a throw weight or some other method,
loop the Paracord over the end supports.
12.
Using a Bowline or similar knot, tie Paracord to
the Carabiners at the ends of the Antenna
Wires.
13.
If a center support is available, use a Bowline or
similar knot, tie one end of the Paracord to the
Carabiner from step (4).
Attach the Termination Resistors. Refer to figure (3)
for steps (14)
–
(19).
14.
Remove the Counterpoise Wires (c), and
Termination Resistors (g) from the Backpack.

Connect the Carabiners at the ends of both
Antenna Wires to the Resistor Eyebolts (q) of
both Termination Resistors.
16.
Connect the Wire Connectors from both
Antenna Wires to the Resistor Connection (p).
Tighten the wing nuts finger tight.
Attach the Counterpoise Wires.
17.

the Wire Connector end of both the
Counterpoise Wires.
18.
Connect the Carabiners to the Resistor Eyebolts
of the Termination Resistors.
19.
Connect the Wire Connectors to the Resistor
Connections of the Termination Resistors.
Tighten the wing nuts finger tight.
Raise the antenna.
20.
Raise the antenna to the desired height and
secure the free ends of the Paracord to the
supports with a Round Turn and two Half
Hitches or similar knot.
21.
Perform operational test.
Sloping Wire
The CHA TD Sloping Wire configuration, see figure (5), is a broadband medium range HF antenna. It should provide
acceptable ground wave and sky wave propagation. This configuration is predominately omnidirectional, slightly
favoring the direction of the low end of the antenna on lower frequencies, broadside around 10 MHz, and the high
end of the antenna on higher 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 25 to 40 feet for best
performance.
Site Selection and Preparation.
1.
Select a site to deploy the CHA TD Sloping Wire
configuration, see figure (5). The best site
should have a tree or other support that would
enable the Termination Resistor 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.
Remove the Matching Transformer (a), Paracord
(h), one Antenna Wire (b), Coaxial Cable (j), two
Stakes (i), both Counterpoise Wires (c), and one
Termination Resistor (g) from the Backpack (s).
3.
If not already attached, connect a Carabiner to
each end of the Antenna Wire.
4.
If not already attached, connect a Carabiner to
the Wire Connector end of both the
Counterpoise Wires.
