Overview

The Tenmory ADS-B Antenna is a dedicated outdoor antenna for receiving aircraft transmissions on 1090 MHz and 978 MHz bands. With a 5 dBi gain and N-type female connector, it offers solid performance for hobbyist aviation enthusiasts who want to track aircraft from home. The antenna is made of fiberglass for weather resistance and comes with a mounting bracket for poles up to 5 cm in diameter. Included in the package is a 10-foot (3-meter) N-male to SMA-male cable, making it easy to connect to popular SDR receivers like RTL-SDR dongles, Airspy, or HackRF. This antenna is a great entry-level choice for anyone looking to improve their ADS-B reception range beyond what a small indoor antenna can provide.

Connectivity & Compatibility

The antenna features an N-female connector. The included cable converts it to SMA-male, which is the standard connector for most software-defined radios (SDR). It is compatible with any receiver that accepts SMA input, including RTL2832U-based USB dongles, FlightAware Pro Stick, and RadarBox receivers. The impedance is 50 ohms, matching standard coaxial cable systems. The supplied cable is 10 feet long, which is generally sufficient for routing from the antenna on a balcony or roof to an indoor receiver. If you need a longer run, you can use an N-female-to-N-male extension cable. Note that the included cable is fixed with N-male and SMA-male connectors, so adapters may be required for other connection types.

Product Info

This product was first listed around 2021 and is available on Japan. The price is approximately ¥8,364, which is reasonable for a dual-band outdoor ADS-B antenna. The manufacturer is Tenmory, and the antenna comes with a one-year warranty (check the listing for details). The package includes the antenna, mounting bracket, and the 10-foot N-to-SMA cable. In terms of market positioning, this is an entry-level to mid-range product. It doesn't compete with high-gain professional antennas, but it offers good value for hobbyists. The dual-band capability (1090 and 978 MHz) is a plus, as many cheaper antennas only cover one band.

Best Use Cases

Aviation enthusiasts: If you use an RTL-SDR to track aircraft with software like ADSB# or Virtual Radar Server, this antenna will significantly improve your reception range compared to a basic indoor antenna. It's a no-brainer upgrade for under $60. FlightAware contributors: For those who feed data to FlightAware or ADSBexchange, a good outdoor antenna is essential for picking up distant aircraft. The Tenmory antenna offers a good balance of gain and cost. * Hobbyist aircraft monitoring: Even if you just want to see what's flying overhead, this antenna provides reliable performance. It's easy to mount and the included cable simplifies setup. However, it's not ideal for professional use or extreme long-range reception. For that, you'd need a higher-gain antenna with a mast-mounted preamp. Also, if you live in an apartment with no outdoor mounting option, you may need to consider a smaller antenna or a different mounting solution.
