HK-VSOF01 VHF single cavity band-pass filter applies to building civil aviation communication system. It can improve the selectivity of receivers. When multiple transmitters share one antenna, it can help improve the isolation degree between transmitters, suppress out-of-band noise and avoid intermodulation interference effectively.
