Nooelec SAWbird+ ADS-B: Premium, Dual-Channel, Cascaded Ultra-Low Noise Amplifier (LNA) & Filter Module for Airplane Tracking Applications. 1090MHz (ADSB) and 978MHz (UAT) Center Frequencies

I'm not usually a review writer, but seeing as this is new and unreviewed, I'd add mine.Bottom Line: It works. It's easy. See the images one is "before" and one is "after" adding the unit. It basically doubled my range. (Your mileage may vary based on location).I'll start by saying my unit arrived and had the silkscreens on the "output" side reversed. I sent an email direct to Nooelec with this, and they replied within an hour saying it was a known thing on the first batch, apologized and explained how to get it connected correctly. Well done.Performance: I just plugged and played. I didn't change anything in my setup. The antenna coax goes to the LNA, and then a 6" cable to my SDR. I'm currently only using the ADS-B/1090mHz side. I'm powering the unit thought the micro USB with a standard Pi wall wart PSU. I have the antenna mounted on my chimney with about a 15ft run of cable. I live in a heavily wooded area and this really helped reception. I basically went from 50nm to right above 100nm. It also picks more lower level traffic closer to my location as well. On the average afternoon I went from ~10 visible aircraft on average to 25+.I'd say it's worth the investment.

I wanted to simplify my setup and add 978mhz. This increased my 1090mhz range slightly and works well for UAT. I have no doubts this is one of the best LNA’s on the market. You get what you pay for. Range is as far as 275nmi with a roof antenna.

What an upgrade to my ADS-B (both 1090 and 978 antennas). This amplifier has taken me from 5000th on FlightAware, to 500th (see picture). My reach now extends from Memphis to Cleveland. At 1000ft MSL with my antennas in the rafters of my house (not even an external implementation).Stupid simple installation.

I really loved this, It was working amazingly well, powered off of USB, until it apparently just died one day. Was running 24/7 for about 9 months, in a dry/warm environment. Pretty disappointed at this price point it would just die and be well past the warranty period.When it worked, it increased my reception range in both bands extremely well. When it dies (of course, installed in a remote location 45 minutes away) it absolutely destroyed reception until I could remove it.Edit: I contacted the manufacturer and asked them for any troubleshooting tips, after sending them a few pictures and a description of its state, they sent me a brand new one.

It does an amazing job enhancing signal reception for an ADSB antenna. I’m getting 1090 up to 250 nm.

I have a somewhat challenging environment where I can't deploy appropriate antennae out-of-doors, however I'm in a good physical location for receiving ADS-B traffic and this has proven to be exactly what I needed to improve my ADS-B for both Mode-S (1090Mhz) and UAT (978Mhz).

I had high hopes for this preamp, but unfortunately in my situation it barely improved signal strength and then after less that two weeks it failed entirely. My setup is a Raspberry Pi running the ADSBExchange image, connected to both the 1090 Blue and 978 Orange ADSBExchange SDR dongles. I was running 42 dB gain on the blue stick and then after installing the SawBird lowered the gain on the SDR to about 3 dB (using higher gain on the SDR's internal LNA, and using no gain, both resulted in worse performance than no SawBird at all. You can see in the performance graph attached the results -- it's difficult to see an improvement but it seems like it's there. Likely I'm limited by surrounding terrain, and despite being in an urban area I don't have enough out-of-band signals to make the SAW filters help much. In any event, I was happy with the very slight improvement, however after less than two weeks performance suddenly dropped. I checked and both white indicator LEDs were dark despite the unit having good USB power. Removing the SawBird and going back to the SDR's internal LNA restored the signals to previous levels. So -- like one of the reviews below, it looks like mine burnt out after a few weeks also. I'll see if I can return it for a refund!

Using this to run both 1090 and 978 mhzs SDRs off a single antenna, worked perfectly off the bat with no adjustment needed for my previous dual antenna setup on my Pi.Testing this before hooking it up to a single antenna though, I did see a noticeable improvement on range as I did not have any bias tree power or filter in line on my setup before.
