DF Antenna with Integrated Monitoring
DF-A0068
The DF-A0068 direction finding antenna covers a frequency range of 20 MHz to 1.3 GHz. An integrated monitoring antenna, working up to 1.3 GHz, gives a high sensitivity omni on the same axis as the DF antenna, without interference between them.The full-size elements on all bands give excellent DF sensitivity. Ultimate angular resolution for strong signals is well under 1° for most of the frequency range. Dipole elements provide good crosspolarisation rejection, and fair performance for signals arriving from up to 15° above or below the horison. The integrated monitoring antenna is mounted above the band 2 DF antenna. A large passive bi-conical antenna, it gives good sensitivity over the whole frequency range. This DF antenna is designed to be used with a 2-channel or 5-channel phase-sensitive receiver, and correlative algorithm. Characterisation of the antenna can be performed on request.
