The DF-A0168 is a wideband portable DF antenna suitable for fixed and mobile mast-mounted applications.
The antenna has a loop array for good DF performance at low frequencies where the phase size of the array is small and three pentagonal arrays for the higher frequency ranges. A secondary pentagonal array of dipoles are combined by an internal 5-way low-loss combiner to provide a good omni from 1 to 500 MHz and an integrated biconical antenna provides a second omni from 500 to 6000 MHz. Improved sensitivity for low frequency monitoring can be accomplished by the optional MONO-A0059 whip attachment which can be fitted to the top of the antenna.
A decagonal cylindrical cavity inside the antenna, approximately 350 mm wide by 370 mm high, allows switching, amplification and RF processing to be integrated into the antenna, reducing cable loss and weight. The cavity slides open giving access to the RF unit. This can be done by one person, on a mast, without a crane.
