FM Bandstop Filter Aviation Frequency Interference Signal Disturbance 50DB Attenuation for SDR
Description:
This filter rejects signals between 88-108MHZ with approximately 50dB or greater attenuation. Broadcast FM bandstop filter can be used with SDR. In some areas, the broadcast FM signal is very strong, overloading the SDR and thus causing very poor performance in other frequency bands. If you see a picture of a BCFM station when you increase the gain, it looks like interference from a WFM signal at other frequencies. It can be determined whether this is the case.
Features:
- The filter mainly filters out FM to prevent its influence on shortwave
- The pit of this filter is relatively deep, and it will also affect the aviation frequency
- Weight: 25g
- Size: 27.5mm*25.5mm
Package Included:
- 1 x Filter
- 1 x Connector Adapter
