Configuration.
Site Selection and Preparation.
1.
Select a site to deploy the CHA HYBRID - MINI /
MICRO
Inverted “L”
configuration. The site
must have two supports that will position the
corner of the “L” and the
end of the Antenna
Wire at a height of about 25 feet. If the right
supports are unavailable, any convenient
objects, such as fence posts or the tops of
vehicles, may be used as a field expedient
supports with reduced performance.
Refer to plates (1) through (3) for the following steps.
2.
If not already attached, connect a Carabiner (d)
to the Isolation Loop (c) at the Wire Connector
(f) end of the Antenna Wire (b).
Connect the Hybrid Base.
3.
Temporarily remove the Antenna Shackle (k)
from the Antenna Connection (h).
4.
Place the Wire Connector from the Antenna
Wire over the Antenna Connection and replace
the Antenna Shackle. Tighten the nut snugly.
5.
Connect the Carabiner from the Antenna Wire
to the Antenna Shackle.
6.
If using a counterpoise wire, connect it to the
Counterpoise Connection (i). Tighten the nut
(not supplied)
snugly.
7.
Connect a CHA RFI CHOKE and coaxial cable or
the Integrated RF Choke end of the CHA Coaxial
Cable assembly to the UHF Socket (g) on the
Hybrid Base.
Raise the Antenna.
8.
Using a Bowline or similar knot, tie the end of a
short length (around 4 feet) of Paracord to the
Carabiner.
9.
Drive a Stake into the ground near the location
closest to the radio set and tie the Paracord
from the Hybrid Base to the Stake using two Half
Hitches, or similar knot.
10.
Using a Fisherman’s Hitch or similar knot, attach
a long length (50 feet or more) to the Antenna
Wire around 25 feet from the Hybrid Base (a).
This will form the corner of the “L”
11.
Using a throw weight or some other method,
loop the Paracord over the support closest to
the radio set.
12.
Using a Bowline or similar knot, tie a long length
of Paracord to the Insulator (e) or Isolation Loop
at the end of the Antenna Wire.
13.
Using a throw weight or some other method,
loop the Paracord over the other support.
14.
Pull the Paracord at the radio set end until the
Antenna Wire is at the desired height and
secure it to the support using a Round Turn and
two Half Hitches, or similar knot.
15.
Pull the Paracord at the end of the Antenna
Wire, such that the Antenna Wire is not quite
taut, and secure it to the support using a Round
Turn and two Half Hitches, or similar knot.
