The DFS-A0245 is a wideband DF antenna system intended for on-the-move direction finding from 1 – 6000 MHz.
The antenna array is implemented as a three-band vertical stack with the low frequency band integrated into a quad-pod with its performance enhanced with patented hybrid loop-Adcock technology to provide improved sensitivity vs traditional designs of the same form factor.
The antenna presents patterns suitable for the Watson Watt estimation method, as well as 3/2-channel correlative DF.
Mounting of the VUHF module is directly via the base-mounted MIL DTL 38999 connector interface onto the quad pod housing the HF band.
A cavity inside the antenna houses an integrated band switch that allows control and calibration circuitry to be integrated into the antenna. External and internal RF chain calibration is accommodated, and a compass and active GPS antenna with receiver are also integrated in the antenna.
