9.
Attach the Carabiner from the other end of the
Antenna Wire to the Carabiner from step (7).
10.
Attach the Wire Terminal on the end of the
Antenna Wire to the other Antenna Terminal.
11.
Using a Bowline, or similar knot, attach a long
length (50 feet) of Support Line to the Carabiner
from step (7). Your assembly should look like
Figure (2).
12.
If used, connect the ground wire to Ground
Connection (g) on the Matching Transformer.
13.
Connect a CHA RFI CHOKE and coaxial cable or
Integrated RF Choke end of the CHA Coaxial
Cable assembly to the UHF Socket (h) on the
Matching Transformer.
Raise the Antenna.
14.
For each corner of the antenna, using a throw
weight or other method, loop the Support Line
attached to the Insulator or Matching
Transformer over the closest support.
15.
Alternately raise each corner of the antenna to
the desired height, ensuring the antenna retains
a mostly square shape, see Figure (3).
Also, be
sure to not pull the antenna too tight, as you
don’t
want the only thing keeping your trees from
swaying is the antenna wire!
Secure the ropes to
the supports using a Round Turn and two Half
Hitches, or similar knot.

Connect the Ground.
16.
If using a ground, connect it to a ground rod
under the location of the Matching Transformer.
17.
Perform operational test.
Troubleshooting
1.
Ensure Wire Connectors are securely connected to the Antenna Connections.
2.
Inspect Antenna Wire for breakage or signs of strain.
3.
Ensure UHF Plug is 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 greater than 10:1, check antenna tuner or coupler 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 or
coupler.
7.
If still not operational, replace Coaxial Cable assembly.
Most problems with antenna systems are caused by
the coaxial cables and connectors.
8.
Connect a Multi-Meter to the Antenna Wire to check continuity. Replace assemblies that do not pass a
continuity check.
9.
If still not operational, replace Matching Transformer (a).
