ADSBexchange 19 Mhz SAW filter in a blue aluminum case. Insert this between your antenna and receiver if you are experiencing interference from local RF signals. Note, this only passes 19Mhz ADS-B signals, not 978. Only needed if you have local RF interference, commonly caused by mobile phone towers or other sources.
SMA Conectors
Allows 1090 Mhz to pass through. Blocks other frequencies.
Does NOT pass 978 Mhz
Customers say
Customers report that the saw filter greatly increases range and improves ADS-B reception. The build quality and filter performance receive mixed feedback, with some finding it high quality while others consider it junk. Customers appreciate the minimal noise level, with one noting it performs well in high EMI/RF noise environments.

A must in urban areas.
Its been so far 3 weeks since installing this filter. I think for anyone who lives in city where there is lots of other RF noise this is a must if you are using those cheap SDR receivers for ADSB reception and data feeds. In my case it double the number of aircraft I’m able to receive. To my surprise it also extended my range probably by about 20nm. Thinking about it, it does make sense. When strong signals outside of the 1090MHz overpower the receiver then it will loose the sensitivity…

Works great

Awesome buy
Cleaned up the signal. Reaching out about 210miles. Around 180 before.

Performed exactly as hoped
I’m running a poorly tuned, leftover antenna, not high off the ground, outdoors with a major obstruction covering almost 180deg to one side and near a big batch of cities with a lot of radio noise. I’m under busy airspace so get lots of local strong signals, but my mid to longer range often tends to be affected by the noise level (which you can infer by a lot of aircraft coming and going within that range in areas you frequently get pretty strong signals). I picked up ADSBx’s filter as a quickly available test to see if I’d get much improvement from some inexpensive noise filtering. As a comparison, I already have a positive experience in this location with a decent filter making a big difference on DTV reception.Results are visible in the graphs. The filter was installed almost right at noon, which only took a couple of minutes.On the signal graph, it almost looked right off the bat like I lost signal. However, a few minutes watching the setup proved that wrong. First, my local strong signals (the stuff flying directly overhead within 10mi or less) showed no visible change at all. Not a huge surprise with how strong those are, but at least the filter wasn’t introducing big losses. Next, my average noise at the time of install dropped from roughly -29 to -31. Not a big difference, but definitely a decrease. At first I thought that was just overall loss through the filter, since my lowest signal and my middle half also both dropped quite a bit. However, that lowest signal represets the weakest signal during that graph period that the radio was able to decode and read, and that improved from -24 to -27 or so, with one signal getting decoded at -28.8. That means the radio is now successfully decoding a lot of weak signals that would have been noise before.The other two graphs back up that conclusion. My average maximum range that morning was around 100nm, but installing the filter immediately and visibly bumped my average max up to around 115-120, which is where it has stayed in the time since install. My number of aircraft tracked also jumped almost 50%, representing a lot of aircraft flying through the edges of my range and getting picked up briefly that would have been lost before.Overall, good performance and worth the pretty darn low price. This is staying installed.A few other reviewers complained about no signal getting through – check your graphs, you may have just gotten a defective unit. That will be obvious because your strongest signals will drop, a lot. Recommend you just return as defective and get a replacement if that happens.

Did I get a faulty piece?
VSWR about 1.8 on the input side (antenna) and insertion loss of about 4.2 dB (through) at 1090 MHz, would not recommend.

Improves ADS-B reception.
The filter preformed like it should. The ADS-B signal was cleaner and the number of visible aircraft improved. For the price I highly recommend it.

NOISY: use filter; NOT noisy: DON’T use filter.
Noisy Environments: In noisy RF environments, the 1090 MHz SAW filter (I have 2) noticeably reduced background interference and improved ADS-B reception.Minimum Noise: In quieter setups, I observed a slight signal (less aircraft spotting distance) loss (very slight, this is expected) with the filters in place.Summary: NOISY: use filter; NOT noisy: DON’T use filter.

Excellent.
Cleaned up SNR by like 12dB and added 20 NM to my range.
