Maritime Direction Finding Antenna


The DF-0092 maritime direction finding antenna covers a frequency range of 20 MHz to 3 GHz. Shipped in a compact storage and transport box 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. This DF antenna is designed to be used with a 5-channel phasesensitive receiver, and correlative algorithm. Calibration of the antenna can be performed on request
