Active Monitoring Antenna


The OMNI-A0107 is a dual ultra-wideband omni-directional monitoring antenna making it suitable for general spectrum surveillance. The use of active components in the antenna provide for a compact design. The OMNI-A0107-01 is a single-output version of the antenna to allow the entire spectrum to be covered by a receiver via one N-type female connector. The OMNI-A0107-02 is a passive version of the OMNI-A0107 utilising two RF connectors.
