Compact DF Antenna
DF-A0141
Active
The DF-A0141 direction finding antenna from Alaris Antennas originates from the well-established DF-A0062 wideband DF antenna. This antenna is the highest-frequency set covering 3 to 6 GHz. It is suitable for quick deployment as well as fixed applications. The 5-element interferometer antenna is located inside a radome with the electrical connections for the five channels being available at the base of the mast via a MI-38999 connector The antenna is mounted at the top of a spring mounted isolating mast to allow it to clear any obstructions in the nearby environment.
