DF-A0257
Compact Adcock DF Antenna
The DF-A0257 is a tri band, compact Adcock DF antenna intended for manpack direction-finding on the move from 20 MHz to 6000 MHz. The DF-A0257 can also be used with the DF-A0245 quad pod antenna for better low-end performance. The antenna presents patterns suitable for the WatsonWatt estimation method, as well as 3-channel correlative DF (CDF). The antenna offers an omni-channel output that can also be used for monitoring. The DF-A0257 has a low noise amplifier on each channel with passive bypass capability, an integrated noise source or optional external signal can be used for downstream RF chain calibration and also includes a navigation and GPS.
