Valcom Manufacturing Group Inc. AS-4163-URC DUAL CHANNEL UHF DIPOLE SHIPBOARD ANTENNA
The AS-4163_URC dual UHF channel antenna is a rugged, self supporting vertically polarized broadband antenna covering the frequency range of 225 to 400 MHz. This light weight, all purpose antenna can be used in the transmit or receive mode.
The antenna is designed for use under severe environmental conditions encountered in a shipboard environment.
The two independent radiating elements are housed in a single fibreglass radome with an internal fibreglass mounting base. A feed-through cable runs from the base to the top aluminum flange of the antenna so that another antenna type can be mounted on the top flange.
The two antenna channels are high power, balanced dipoles, each capable of handling power levels of up to 1 KW average. The isolation between the two channels is more than 25 dB. Each input channel's VSWR is less than 3.0:1 with an average VSWR of 2.5:1 over the entire 225 to 400 MHz frequency range.
The antenna has been designed and tested to meet the vibration requirements of MIL-STD-167, type I and II, shock requirements of MIL-S-901, and the environmental requirements of MIL-E-16400H.
