The DF-A0085 dual-polarised direction finding antenna covers a frequency range of 20 MHz to 3.6 GHz.
The DF-A0085 dual polarised DF antenna covers a frequency range of 20 MHz to 3.6 GHz.
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 cross polarisation rejection, and fair performance for signals arriving from up to 15° above or below the horison.
The DF-A0085 is capable of HP and VP DF, selectable for Band A and B, with each polarisation requiring characterisation. Two outputs are provided per element on each of bands A and B, one each per polarisation. Band C is polarisation agnostic, allowing concurrent VP, HP and LHCP DF a single characterisation table utilising the array of spiral antennas provided.
This DF antenna is designed to be used as a multi-channel phase sensitive receiver, and correlative algorithm. Characterisation of the antenna can be performed on request.
The DF-A0085 provides a weatherproof interface at the top of the antenna onto which a lightning protection system can be mounted.
