VHF Monitoring Antenna


This wideband manpack antenna covers the full VHF band with some extension to 20 MHz and 520 MHz. By covering the full VHF band in 1 antenna, it replaces 2 conventional high-power antennas, reducing clutter and the visual signature. The matching section at the base of the antenna contains transformers and loading for the whip. This is mounted directly onto an L-shaped mounting bracket and an N-type connector. The whip extends from the top of the matching section. The radiating whip is loaded along its length to control the antenna radiation patterns. The antenna comes with 5 radials, 1.6 m in length that connect into the base of the antenna. These radials make the antenna groundplane independent without compromising on electrical performance.
