FlightAware is excited to announce the availability of a 1090 MHz-only bandpass filter for the ADS-B community outside of North America. This is something many of you have asked for. The filter we’ve offered in the past wasn’t great at blocking GSM mobile phone interference that can be found outside of North America. This new filter is an economical bandpass filter option that provides better attenuation of 950 MHz GSM. Those of you building PiAware sites in urban areas or other areas with 950 MHz mobile phone interference (found outside of North America) may find this very useful. We are pleased to offer this through our retail product launch partners in Europe: ModMyPi and Moonraker and they are available for sale today. We hope to add more retail distribution partners in other areas of the world going forward.
