(3) Connect the replacement halyard to the reel assembly, and raise
the antenna back up.
(4) Connect the halyard to the support.
o. Reel assembly.
To replace
one
of
the
dipole
reel
assemblies,
proceed as follows (see Figure 34):
(1) Remove the wing nut and the antenna wire from the insulator post
on the side of the defective reel assembly.
(2) Disconnect the halyard from the reel assembly.
(3) Remove the antenna wire from the reel assembly.
(4) Connect the antenna wire to the replacement reel assembly.
(5) Connect the halyard to the replacement reel assembly.
(6) Connect the antenna wire over the post on the insulator, and
screw on the wing nut to secure the antenna wire to the insulator.
p. Antenna wires. To replace one of the dipole antenna wires, proceed
as follows (see Figure 34):
(1) Remove the wing nut and the antenna wire from the post on the
insulator.
(2) Remove the antenna wire from the reel assembly.
(3) Connect the replacement antenna wire to the reel assembly.
(4) Connect the other end of the replacement antenna wire over the
post on the insulator, and screw on the wing nut to secure the antenna wire
to the insulator.
20. REPLACEMENT AND REPAIR. Once you have verified a fault in the AN/GRC-
213 and have determined by system troubleshooting which major component is
causing the fault, your problem becomes what to do to repair it.
As a
guideline for this decision, if the malfunctioning unit is the mount, the
receiver-exciter, the amplifier-power supply (with the exception of the knob
or lamp), or the amplifier-coupler, you must fill out DA Form 2407
(Maintenance Request) and forward the unit to the DS unit for repair. If
the defective component is an audio accessory, an antenna, or a cable, you
can repair or replace it.
a. Replacement.
Replacement instructions for audio accessories,
cables, and antennas are in paragraph 19.
Replacement of the mount,
receiver-exciter, AMP-coupler, and AMP-power supply requires that you
prepare DA Form 2402 (Exchange Tag), DA Form 2404, and DA Form 2407, turn in
the malfunctioning component to your DS activity, and receive a replacement
on direct exchange. The knob and lamp of the AM-7152/GRC-213 are the only
replaceable items of these four pieces of equipment at organizational level.
