BandGuard Meshtastic Notch Filter
These filters are specifically tuned to reject out of band interference which causes your mesh radios to perform poorly. Installation of the bandguard filter between your mesh radio and antenna is like giving your radio a new set of ears. Hear stations better and more reliably than you did before.
Typically the radios used in LoRa radios that are used in Meshtastic do not have any front end filtering on the receiver. Even though the radio is listening on one frequency, the circuitry still hears everything including Cellular, Paging and other much more higher powered transmitters which operate near the 902Mhz ISM band. This filter rejects those signals while allowing the frequency you want to hear to pass through.
