The DF-A0147 is a wideband DF antenna suitable for rugged applications. Based on the more portable DF-A0095 product, the rugged version features an upgraded mechanical and environmental design for marine use.
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 bi-conical antenna provides a second omni from 500 to 9000 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.
