DF Antennas

The DF-A0095 is a wideband portable DF antenna suitable for both fixed and mobile mast-mounted applications. The antenna features 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 dipole array is internally combined by a low-loss 5-way combiner to provide a good omni pattern from 1 to 500 MHz, and an integrated biconical antenna provides a second omni from 500 to 6000 MHz.

A decagonal cylindrical cavity inside the antenna, approximately 350 mm wide by 370 mm high, allows for the integration of switching, amplification, and RF processing within the antenna, reducing cable loss and weight. The cavity slides open to provide access to the RF unit. This can be done by a single person, on a mast, without the need for a crane.

Small carrying handles molded into the base of the antenna allow it to be safely moved by two people. The antenna has internal struts and gas lifts, enabling one person to access the RF switch cavity without removing the antenna from the mast. The radome and antenna can be lifted and separated from the switching panels and connectors.
