LoRa Meshtastic 906.875 MHz Long Fast Cavity Filter – New – USA 4 MHz BW
These filters are new and unused and were one of a prototype batch. These filters are also tunable to other frequencies within 890 to 960 MHz with a possible narrow bandwidth of 4 MHz. You might see a small drop in RSSI due to the filter loss, but the SNR / CN ratios will increase dramatically resulting in more nodes being seen.
