DF-A0121

Compact Dual Band Direction Finding Antenna

Part of the Alaris Antennas product range

Download datasheet

The DF-A0121 direction finding antenna from Alaris Antennas originates from the well-established DF-A0062 wideband DF antenna. This antenna is the highest-frequency set, which works well from 400 to 6000 MHz. It is suitable for quick deployment as well as fixed applications. The 5-element DF array is located inside a radome with the electrical connections for the ten channels being available near the base, via the enclosure at the base of the antenna. The antenna also includes a dedicated Monitoring channel.
