This neat little 3DBi ADS-B 1090Mhz SMA Antenna with Magnetic Base is designed to receive ADS-B data from aircraft! It features an SMA Male connecter, so it's compatible with all ADS-B receivers including FlightAware Dongles, PiAware, Mode S Beast, Radarcape, Kinetic SBS1/SBS3, RTL Dongles, and more. It's designed to attach neatly to an internal metal surface and track planes as they drift on by.
Customers should be aware that ADS-B signals do not penetrate solid surfaces well, and the antenna should be placed high and next to a thin external surface e.g. a window. Don't expect this to work well through 12" of brickwork!
