The DF280B is a tactical Direction Finding (DF) antenna system with high sensitivity. The DF280B is used with DRT receivers to locate the source emitters for signals in the 600 MHz to 3000 MHz frequency range. Commutated DF is the standard method for most signals of interest, but this system can also perform Instantaneous DF (IDF) on short-duration signals.
The DF antenna connects to the DRT receiver using coaxial RF and control cabling. The Beamformer (BF2) has an integrated electronic compass, an external GPS antenna connection, and an ultra-wideband omni antenna. The system is powered through the DRT receiver. It can be mounted in a variety of ways. The DF280B is weather-resistant for continuous outdoor operation and is water resistant to 1 meter for a period of 30 minutes.
The DF280B model provides the beamformer and array as separate components. This allows the DF280B antenna array to be as small as possible.
