The OMNI-A0245 is a passive monitoring antenna designed to operate in the 20 to 520 MHz frequency band. It is mounted on a connector base, with a matching unit at the base, a spring for shock absorption and flexibility, and has a thin steel whip. The radiating whip is loaded along its length to control the antenna radiation patterns. It is thin and flexible over most of its length, with loads protruding slightly. The whip will not be damaged by contact with trees, overhead objects, etc., in normal operation.
