Review on 📡 Enhanced High Gain Antenna Set for Stratux ADS-B - 1090MHz & 978MHz Labeled Bundle for SMA and MCX-Connected Software Defined Radios (SDRs) by Jeremiah Small

I bought these antennas hoping they weren't just cheap Chinese WiFi antennas rebranded for ADS-B/UAT frequencies. I was not disappointed. I placed both antennas in a VNA and they were both fine tuned to the specified frequencies: 1090MHz and 978MHz. The UAT/978MHz antenna had a VSWR of 1:1.09, while the ADS-B/Mode S/1090MHz antenna had a VSWR of approximately 1:1.3. Suppliers are small businesses owned by service veterans, which is another reason to buy from CrewDog Electronics.
