144-148 MHz Bandpass Filter for 2m Band RF Adapter 7 dB in the pass

7 dB in the pass band

LoRa and sub-GHz IoT sensor networks

is greater than 45 dB and typically close to 50 dB

The 169 MHz band's low frequency gives strong building penetration and extended range compared to the more common 868 MHz wM-Bus band

144-148 MHz Bandpass Filter for 2m Band RF Adapter 7 dB in the passPRODUCT OVERVIEW The GPIO Labs 144148 MHz Bandpass Filter (board only) protects 2m band receivers from out of band interference strong FM broadcast, cellular, and adjacent service signals that desensitize front end amplifiers and mask weak signals. Passband covers 144148 MHz (North South America, Hawaii, Asia, Oceania) and 144146 MHz (Europe, Africa, Russia), matching regional 2m allocations for amateur radio, satellite communications, APRS, and VHF
