The OMNI-A0244 is a compact vehicle-mount monitoring antenna. Supplied in both active and passive versions, it allows monitoring over the full 20 to 6000 MHz band. It is mounted on an N-type connector base, with a spring for shock absorption and flexibility. The active version of the antenna includes a nominal 10 dB amplifier to help overcome cable loss. The passive version has no amplifier, and is less expensive, and has no dynamic range limitations.
