THE BROADBAND OMNIDIRECTIONAL ANTENNA OE-254
The broadband omnidirectional VHF antenna system OE-254 is al antenna that will replace
the antenna, RC-292. The antenna permits operation in the 30 to 88 MHz frequency range
without the need to manually drop and retrieve the antenna each time the operating frequency
is changed. The antenna system is fielded for use with current tactical VHF-FM net radios.
The antenna system is being issued on a one-for-one replacement for the RC-292.
This omnidirectional vertically polarized VHF antenna system--O Operates in the 30 to 88 MHz range without any physical adjustments.
O Has input impedance of 50 ohms unbalanced with an average voltage standing wave ratio
(VSWR) of 3:1 or less at RF power levels up to 350 watts.
O Is capable of being assembled and erected by one individual.
O Operates at a distance equal to that of the present antenna equipment RC-292.
O Meets the broadband and power handling requirements of the 2-port and 5-port transceiver
multiplexer.
O Is capable of being used with the Steerable Null Processing Group OL-275()/VRC SNAP-1
The antenna system includes:
O A standard lightweight mast having a maximum height of 41 feet and 9 inches.
O A canvass carrying bag similar to that issued with antenna equipment RC-292. Assembly
and erection procedures are provided with the bag.
O All necessary guying assemblies, stakes, base plate, tools, and other ancillary equipment
required to make a complete antenna system.
O All necessary coaxial cables and cable adapters for Radio Set AN/PRC- 25 and AN/PRC-77
(series) and the AN/VRC-12 (family).
