This 9 dBi rubber whip antenna is tuned specifically to 1090 MHz, the frequency used by Mode S ADS-B (Automatic Dependent Surveillance–Broadcast) transponders in commercial and general aviation aircraft. It connects directly to any SDR receiver or dedicated ADS-B decoder with a standard SMA female port, including FlightAware Pro Stick, RTL-SDR Blog v3, and similar dongles used for aircraft tracking with PiAware or dump1090 on Raspberry Pi.
At 9 dBi gain and 375mm length, this antenna provides significantly better range than the short stub antennas typically bundled with RTL-SDR kits. The higher gain narrows the vertical beam angle, concentrating reception energy toward the horizon where aircraft are most likely to appear, rather than wasting gain on sky directly overhead. The foldable hinge allows the antenna to be positioned at 0°, 45°, or 90° to suit different mounting locations — desk, shelf, or window — without needing a separate bracket.
This antenna is tuned for 1090 MHz only and is not suitable for 978 MHz UAT (Universal Access Transceiver) used by some general aviation aircraft in the US. For dual-band 978/1090 MHz coverage, a separate wideband antenna is required. Verify your SDR dongle has an SMA female port (hole in center) before ordering — some dongles use MCX or BNC connectors and would need an adapter.
Frequently Asked Questions
ADS-B (Automatic Dependent Surveillance–Broadcast) is a surveillance system where aircraft continuously broadcast their GPS position, altitude, speed, and identification on 1090 MHz. Ground receivers capture these broadcasts to track aircraft in real time. A resonant antenna tuned to exactly 1090 MHz is far more efficient at capturing this signal than a general-purpose wideband antenna — the resonant length of 375mm is a quarter-wavelength at 1090 MHz, which maximizes signal reception at that frequency.
A typical RTL-SDR stub antenna has 2–3 dBi gain. At 9 dBi, this antenna has approximately 6 dB more gain, which roughly doubles the effective reception range in ideal conditions. In practice, users switching from a stock stub to a 9 dBi 1090 MHz antenna typically see aircraft count per hour increase by 2–4x and maximum range increase from around 100–150 nautical miles to 200–300+ nautical miles, depending on antenna placement height and local terrain.
Yes. The FlightAware Pro Stick has an SMA female port that accepts this SMA male antenna directly. PiAware is software that runs on Raspberry Pi — the antenna connects to the Pro Stick or any compatible RTL-SDR dongle attached to the Pi. No adapter is needed for the Pro Stick or RTL-SDR Blog v3 dongle.
Antenna placement height is the single biggest factor in ADS-B range. Moving the antenna from a ground-floor window to a rooftop can increase range dramatically. This antenna body is weatherproof enough for short outdoor exposure, but the SMA connector junction should be protected with self-amalgamating tape for any permanent outdoor installation. For rooftop use, connect via a low-loss coaxial cable (RG58 or better) rather than placing the SDR dongle outdoors.
No. This antenna is resonant at 1090 MHz and is not optimized for 978 MHz UAT, which is used by some US general aviation aircraft equipped with ADS-B Out on the UAT band. To receive both 1090 MHz and 978 MHz, you need either a wideband antenna covering both frequencies or two separate antennas connected to two separate SDR receivers running simultaneously.
The 2-pack is useful for users running dual-frequency ADS-B setups (one receiver for 1090 MHz, one for 978 MHz UAT — though this antenna only
