FlightAware 1090 MHz antenna In December 2018, I started participating in FlightAware's network of radio receivers that track aircraft. I have an antenna on a rock in my back yard connected to a Rasbperry Pi with a USB radio receiver. See FlightAware's ADS-B page for more information on their tracking network.

My username on FlightAware is tom239. I'm happy to compare notes with others operating FlightAware receiver sites; my email address is on my contact page.

I am using: Flightaware offers USB receivers with and without 1090MHz bandpass filters. The filter is definitely recommended in urban areas; in rural settings the choice depends on how strong various other RF signals are in your area. I tried both and got better results with the filter.

The Ethernet switch I'm using gives the option of either 10 or 100 Mbps on its PoE ports. I chose 10Mbps because that's already more bandwidth than this application needs and 10Base-T is more reliable over long cable runs (in this case, about 70 meters).

The PoE switch draws about 3 watts without the Raspberry Pi connected and about 8 watts with it connected and running.

I'm located between two mountain ranges. Terrain limits reception in most directions, as seen in the lopsided coverage graph on my statistics page.
