When it comes to selecting the best SDR (Software-Defined Radio) dongle for ADS-B (Automatic Dependent Surveillance-Broadcast), there are several popular options known for their performance and compatibility. Let’s take a closer look at five top contenders: ADSBExchange Blue, AirNav RadarBox FlightStick, Nooelec NESDR Smart, SDRplay RSP series, and Airspy Mini
- ADSBExchange Blue: Designed specifically for ADS-B reception, the ADSBExchange Blue dongle is highly regarded for its outstanding performance. Equipped with a built-in low noise amplifier (LNA) and SAW filter, it enhances signal reception and reduces interference. It excels in range and sensitivity, making it an ideal choice for tracking aircraft over considerable distances. It is compatible with various software packages, offering reliable performance and ease of use.
- AirNav RadarBox FlightStick: Another popular option is the AirNav RadarBox FlightStick, which shares similarities with the ADSBExchange Blue dongle. It features a built-in LNA and SAW filter to improve signal reception. With its compatibility and ease of use, it supports multiple software packages and platforms. The FlightStick delivers reliable performance and offers good range, making it a solid choice for ADS-B tracking.
- Nooelec NESDR Smart: The Nooelec NESDR Smart appeals to SDR enthusiasts due to its affordability and decent performance. While not designed specifically for ADS-B, it covers a wide frequency range, allowing exploration beyond ADS-B. The NESDR Smart incorporates a built-in LNA to enhance signal reception, though its amplification capabilities may be less potent than dedicated ADS-B dongles. It is compatible with most SDR software and is recommended for budget-conscious individuals or beginners.
- SDRplay RSP Series: The SDRplay RSP series, including models like RSP1, RSP1A, RSP2, and RSPdx, offers advanced SDR receivers with exceptional performance. While not explicitly tailored for ADS-B, they boast high sensitivity, dynamic range, and wideband coverage suitable for various radio applications, including ADS-B reception. The SDRplay RSP devices provide extensive customization and advanced signal processing options, appealing to users seeking a versatile SDR solution beyond ADS-B.
- Airspy Mini: The Airspy Mini is a popular SDR (Software-Defined Radio) receiver known for its exceptional performance and wide frequency range coverage. While it is not specifically designed for ADS-B (Automatic Dependent Surveillance-Broadcast) reception like dedicated ADS-B receivers, it can still be used effectively for ADS-B tracking. Here’s some information about using the Airspy Mini for ADS-B
When choosing an SDR dongle for ADS-B, it’s essential to consider factors such as performance, compatibility, and budget. The ADSBExchange Blue and AirNav RadarBox FlightStick are dedicated ADS-B receivers with reliable performance. The Nooelec NESDR Smart is an affordable entry-level option, while the SDRplay RSP series and Airspy Mini offer advanced capabilities and versatility for broader radio applications.
Before making a decision, research specific models read user reviews, and evaluate your requirements and budget. The best SDR dongle for ADS-B depends on your needs, desired performance, and overall budgetary considerations. Selecting the right SDR dongle will enhance your ADS-B tracking experience and open doors to the fascinating world of software-defined radio.
The FlightAware Pro Plus should be listed as well. Difference between this one and the RadarBox Flight Stick is the positioning of the filter: the FA Pro + has the filter between the LNA and the SDR, while the RadarBox Flight Stick has the filter between the LNA and the antenna. As a result, the RB SDR will work better in noisy, urban environments while the FA SDR is better in less noisy places.
Also, in my experience, the heat handling of the FA SDR is better than the RB SDR; I’ve had several of the RB SDRs stop working after about a year deployment. Most of the FA Pro+ SDRs are still running after 3-4 years of unattended deployments. (I run about 6 ADSB feeders of which 5 are remote only)
