The DF-A0122 direction finding and monitoring antenna is designed for 5-channel phase-sensitive receivers to DF using correlative algorithm over a frequencies of 20 to 410 MHz.
Full-size elements give excellent DF sensitivity, yielding angular resolution for strong signals well under 1 degree for most of the frequency range. Dipole elements provide good cross-polarization rejection and fair performance for signals arriving from up to 15 degrees above or below the horizon. DF antenna calibration can be performed on request.
Shipped in a compact storage and transport box, the antenna can be assembled by one person in 20 minutes, without special tools.
