View source for RC-292

Antenna Equipment RC-292 is an elevated, wide-band, modified ground-plane antenna designed to increase the distance range of radio sets in 30 to 76 mHz range.

The RC-292 can be used with the following typical radio sets:
# Radio Sets AN/VRC-12, AN/VRC-43 through AN/VRC-49 (TM l1 5820-401-12).
# Radio Sets AN/VRC-53, AN/VRC-64, AN/GRC-125, and AN/GRC-160 (TM 11-5820- 498-12).
# Radio Sets AN/PRC-25 (TM 11-5820- 398-12) and AN/PRC-77 (TM 11-5820-667-12).
