Rugged Wideband DF Antenna
DF-A0088
The DF-A0088 is a wideband DF antenna suitable for rugged applications. Based on the more portable DFA0095 product, the rugged version features an upgraded electrical, mechanical and environmental design for marine use. The antenna has a redesigned loop array for good DF performance at low frequencies where the phase size of the array is small and three pentagonal dipole-based arrays for the higher frequency ranges The monitoring function is provided by means of a removable whip antenna for the 1 MHz to 60 MHz band, a pentagonal dipole-array for the 50 MHz to 500 MHz band and an integrated bi-conical antenna provides the coverage from 500 MHz to 6000 MHz 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. A suggested switch for integration with the DFA0088 is the DF-A0226 which is a 1MHz to 6000 MHz 4- Band Switch.
