complexity of site selection and setup. Most configuration and frequency combinations will require a wide range
antenna tuner or coupler.
Sloping “V”
The CHA TD LITE
Sloping “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 above
16 MHz. This configuration tends to be bidirectional towards the opening and apex
of the “V”
. It requires only a
single support and can be mounted at heights from 3 to 40 feet, with around 25 feet providing good overall results.
Figure 1. Sloping V Antenna Configuration.
An opening angle of 90° will provide good overall performance, but angles from 180° to 60° can be used to fit the
antenna to the site or to improve performance. Larger opening angles increase performance on lower frequencies
and smaller angles on higher frequencies. At 180°
, the antenna becomes an Inverted “V” antenna.
The antenna
may also be mounted horizontally using three 10 foot tall supports.
Site Selection and Preparation.
1.
Select a site to deploy the CHA TD LITE Sloping
“
V
”
configuration, see figure (1). The best site
should have a tree or other support that would
enable the Matching Transformer 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.
3.
If not already attached, connect a Carabiner (d)
to the Wire Connector (k) ends of the Antenna
Wires.
Connect the Matching Transformer. Refer to figure
(2) for steps (4)
–
(9).
4.
Connect the Carabiner from the Wire Connector
end of an Antenna Wire to the Transformer
Eyebolt (j).
Figure 2. Matching Transformer Electrical and
Mechanical Connections.
5.
Connect the Wire Connector from the Antenna
Wire to the Bottom Transformer Connection (i).
Tighten the wing nut finger tight.
