Feature

●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: The broadcast FM Band-stop filter is more useful when used together with SDR, because in some areas, the broadcast FM is very strong, SDR is easy to overload, resulting in poor performance in other bands
●COME WITH BIDIRECTIONAL INTERFACE: FM band stop filter is equipped with a bidirectional interface, realize aviation frequency suppression interference


Description

Specification:
Item Type: Band Stop Filter
Material: ABS, PCB
Broadcast FM band stop filters are useful in conjunction with SDRs because in some regions the broadcast FM is so strong that it overloads the SDR, resulting in very poor performance in other frequency bands. You can tell if this is the case if you see an image of the BCFM station when you increase the gain that looks like a WFM from other frequencies interfering.

Pay attention to the correct operation.
