The DF-A0158 is a wideband compact DF antenna with a ruggedized design to suit harsh environments and applicationsbrThe antenna uses primarily Adcock type arrays, and incorporates a patented high sensitivity hybrid loopAdcock topology for the lowest frequency band to maintain high sensitivity for its size. Each band offers an omni-channel output that can also be used for monitoring.brBand switching is done by a switch integrated into the antenna. An on-board wideband noise source is provided to allow for downstream RF channel calibration. An on-board electronic compass is provided.brCommunication to, and control of, the antenna is provided by means of RS485 interface. Band switching can also be accomplished via direct differential pair switching for higher speed if needed.
