24. ANTENNA CONNECTION. You now have the radio set mounted. Now you must make all the cable
connections and attach the required auxiliary equipment.
VERIFY THAT POWER IS PROPERLY TURNED OFF BEFORE PROCEEDING.
VOLTAGES WILL CAUSE BURNS IF CONTACT IS MADE WITH THE ANTENNA AND THE RADIO IS
The AN/GRC-213 has four types of antennas that can be used with it. These antennas are the whip, slant wire,
dipole, and NVIS. The type of antenna you choose will be determined by the tactical situation, terrain, and other
operating considerations. These things will be discussed later when you get into the operation of the radio set.
For installation of these antennas, refer to the following:
TM 11-2300-476-14-P for the whip antenna.
TM 11-5820-923-12 for the NVIS, slant wire, and dipole antennas.
25. CONNECTORS AND FUNCTIONS. In the following paragraphs, you will be making the interconnection
required between the components and the mount that you are using with your radio set. The proper grounding of
the radio set also will be discussed.
a. The interconnections for the AN/GRC-213 are performed as follows: (Refer to Figure 12 for
connector and cable locations and Table 7 for the functions.)
Check to see that all connections to the mount have been completed as outlined in TM 11-2300-
476-14-P. Ensure that the POWER switch on the AM-7152 and the OFF/ON switch on the RT-
1209 are in the OFF position before proceeding further.
Connect the primary power cable that comes from under the mount to connector J101 on the rear
of the amplifier-power supply AM-7152.
Connect AN/PRC-104 power cable from J104 on the rear of AM-7152 to the power input
connector on the rear of the amplifier/coupler.
