88-108M band stop filter passive notch filter · Product code P-277

1. This filter is mainly used to filter out FM to prevent its impact on short waves. 2. The pit of this filter is relatively deep, and it will also affect aviation frequencies. 3. Weight: 25 grams 4 Size: 27.5mm*25.5mm This filter suppresses signals between 88-108MHZ with about 50dB or more attenuation. Broadcast FM band stop filters are useful for use with SDRs because in some areas the broadcast FM signal is very strong, causing the SDR to be overloaded, resulting in very poor performance in other bands. You can tell if this is the case if you see an image of a BCFM station when increasing the gain, with interference that looks like a WFM signal at other frequencies.
