Hunter XD logo
Hunter XD is a Near Field RF detector. It operates on a difference in signal level across two H field antennas thus distinguishing between a high power distant transmission as with a TV channel, and a near by low level transmission as with a radio microphone (bug). This antenna array also provides direction finding (DF). With a bandwidth of 10 MHz to 10 GHz, Hunter XD also has a switchable 2.4 – 2.5 GHz 20db attenuator to aid overall signal detection in a strong WiFi environment. Control is with an AMOLED touch screen, thumb joy stick and read out from a high visibility head up LED display. Monitoring is with cordless headphones.
