Wideband Portable DF Antenna

DF-A0095

The DF-A0095 is a wideband portable DF antenna suitable for fixed and mobile mast-mounted applications.brThe 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.brA 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.brSmall carrying handles moulded into the base of the antenna allow it to be moved safely 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 is lifted up and away from the switch and connector panels.
