🚀 Elevate Your Flight Tracking Game!
The AirNav Radar 1090 MHz ADS-B Filter is designed to optimize the reception of 1090 MHz ADS-B signals, ensuring compatibility with any ADS-B receiver featuring an SMA connector. This filter significantly reduces signal loss and interference, making it an essential accessory for users operating near cell towers or other communication devices.

Filter works
I did a teardown of this because there's no markings regarding input and output.The female is the input/antenna side because the ESD protection components are on that side. But it probably filters without ESD protection if installed in reverse.If you have an amplifier it possibly has similar SAW filters already built-in.This filter doesn't improve my reception, but in my setup it is installed to stop transmissions on a nearby VHF/UHF antenna from blowing out the front-end of my SDR. Quick testing with GQRX shows it silencing the FM broadcast band while not (significantly) impacting the 1090 signal, so I'm confident it's doing its job.

Ultimately works well, despite my having not really needed it.
I suspected my signal could improve if I eliminated interference. As it turns out, interference was not really a factor after all, but this filter does indeed work.

Too much loss, but does help filter out VHF/UHF
Does filter well, just tooo much loss like the other reviewer experienced. Even when placed as close to antenna, actually performs better without this filter attached in the 1090 range. Waste of money in my opinion given results.

Great small size, not great performance
The insertion loss with this is more than my FA or other filters. Every test I've done with FA, RB and Airspy dongles from time to time shows poor results with this filter.The small size is great. Just sad it doesn't perform as well as others.
