Airframes 1/4-wave Antenna for ADS-B / UAT

An affordable 1/4 wave antenna center-tuned at 1090 MHz for receiving aircraft transmissions with positional information, ideal for ADS-B.

This antenna when paired with an SDR is ideal for decoding ADS-B transmissions for use with aggregator sites like airplanes.live or plane.watch, though will work with any ADS-B aggregator (AirNav Radar, FlightAware, FlightRadar24, ADSB Exchange, etc).
