Compact Adcock DF Antenna


The DF-A0253 is a single band, compact Adcock DF antenna intended for direction-finding from 2000 to 6000 MHz.brThe antenna presents patterns suitable for the WatsonWatt estimation method, as well as 3-channel correlative DF (CIDF). The antenna offers an omni-channel output that can also be used for monitoring. brThe DF-A0253 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 navigation and GPS.
