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. www.alarisantennas.com Alaris Antennas has a policy of continuous improvement and hence specifications m

Compact Dual Band Direction Finding Antenna 400 – 6000 MHz Product Code: DF-A0121 The graph illustrates the direction finding sensitivity of a typical system, modelled using a phase and amplitude correlative DF algorithm. The sensitivity is measured using an IF bandwidth of 1.25 kHz and without averaging. The graph shows the minimum signal required to obtain a bearing fluctuation of less than 1º for the frequency range 400 to 3000 MHz, less than 3º for the frequency range 3000 to 6000 MHz. The values should be adapted for the system in question if it uses a different bandwidth and receiver noise...
