Broadcast FM Bandstop Filter 88 to 108MHZ Block FM Notch Filter Broadcast FM Band Rejection Filter

COME WITH BIDIRECTIONAL INTERFACE: FM band stop filter is equipped with a bidirectional interface, realize aviation frequency suppression interference
REJECT 88‑108MHZ : This filter rejects between 88‑108MHZ with approximately 50dB or greater attenuation
PREVENT INFLUENCE ON SHORT WAVES: This filter is mainly to filter out FM to prevent its influence on short waves, helps a lot in communication system
EFFECT AVIATION FREQUENCIES: This filter also has an effect on aviation frequencies, you can tell if this is the case if you see an image of a BCFM station when you increase the gain that looks like interference from WFM on other frequencies
USEFUL WITH SDR: Broadcast FM band rejection filters are useful in conjunction with the SDR because in some regions the broadcast FM is very strong, overloading the SDR, resulting in very poor performance in other frequency bands
