SAWbird+ ADS-B Dual-Channel LNA & Filter - Boost ADS-B Range

In this review the SAWbird+ ADS-B is examined as a focused upgrade for hobbyist and professional airplane trackers who need cleaner, stronger ADS-B and UAT reception. The primary reason to buy is straightforward: this module delivers a very low noise figure and substantial gain for both 1090 MHz and 978 MHz paths, which translates into noticeably improved signal-to-noise ratio and extended reception range when installed correctly. It is a plug-and-play, preassembled unit that aims at users who already run external antennas and want reliable, class-leading amplification.

Key Features

• Dual-channel 1090/978 MHz: Provides targeted amplification for ADS-B and UAT frequencies so both tracking systems see improved signal strength.
• Ultra-low noise figure: With a noise figure around 0.9 dB or lower, the module improves signal-to-noise ratio for weaker airplane signals at range.
• Substantial gain: Approximately 34 dB to 35 dB of gain on each side boosts reception range when radios are not overloaded.
• Bias tee and USB power options: Offers flexible powering via bias tee on either side or a micro USB port for setups without bias tee capability.
• Excellent out-of-band rejection: Exceptional rejection levels (around +85 dB) help keep adjacent band noise from degrading ADS-B reception.
• Preassembled metal enclosure: Ships in a black aluminum case with SMA adapters and a micro USB to DC barrel adapter for immediate installation.

Who It's For

This module is best for flight tracking enthusiasts, ham radio operators, and small airports that need to extend ADS-B and UAT reception without redesigning an entire front-end. It is particularly useful where weak, distant transponder signals are common and improving SNR will produce tangible gains in range and decoder performance.

It is not ideal for someone who cannot adjust receive gain levels or remove other amplifiers in the chain, since improper gain settings will overload the receiver and reduce or eliminate reception. Those seeking a long-term ultra-durable commercial install should weigh reported short lifespan concerns against the performance benefits.

Pros & Cons

Pros

• Industry-low noise figure increases usable signal range and decoder reliability.
• High gain on both 1090 MHz and 978 MHz channels delivers clear, measurable range improvements.
• Flexible powering with bias tee on both sides or micro USB fits many setups.
• Strong out-of-band rejection keeps unwanted signals from interfering with ADS-B reception.

Cons

• Must reduce gain or remove other amps in the chain to avoid receiver overload; improper setup can worsen reception.
• Some customers report early failures, so longevity may vary despite a 2-year warranty.

Frequently Asked Questions

Do I need to change my receiver settings?
Yes. You must lower receiver gain and remove other amplifiers if present, otherwise the radio will overload and reception may worsen.

How is the module powered?
Either via bias tee power on either side (3 to 5 V DC) or through the included micro USB power option; use only one power source at a time.

Will it work with any ADS-B antenna?
Yes, it is designed to sit after a 50 matched antenna feed and improve SNR for most standard ADS-B and UAT antennas.
