DF-A0300
Folding Direction Finding and Monitoring Antenna
The DF-A0300 direction finding antenna covers a frequency range of 20 MHz to 3 GHz. An integrated active monitoring antenna, working up to 6 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 in two bands, mounted above the Band C DF antenna. These are amplified at the top of the cable, and passively combined to give continuous coverage over the frequency range 20 MHz to 6 GHz, with a single output connector. This DF antenna is designed to be used with a 2-channel phase-sensitive receiver, and correlative algorithm. Characterisation of the antenna can be performed on request.
