Compact Adcock DF Antenna

DF-A0254

Active

The DF-A0254 is a dual band, compact Adcock DF antenna intended for direction-finding from 400 MHz to 6000 MHz. 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-A0254 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 various compass and GPS options.
