The DF-A0300 direction finding antenna covers a frequency range of 20 MHz to 3 GHz.
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 1º for most of the frequency range. Dipole elements provide good crosspolarisation rejection, and fair performance for signals arriving from up to 15º 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.
