Outstanding Filter that Dramatically Increased the Number of Aircraft I See
Outstanding filter! The number of aircraft I now pick up using this filter is 2-3 times what I was getting without it!

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.

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.

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.

Reject the unwanted!
Works as it should with about 30db out of band rejection. It does however have nearly 3.5db of insertion loss so that may be noticeable if you already have a longer run of lossy coax. Overall it did seem to improve my stats slightly. As a follow up comment. I found that after using it a few weeks, overall it had no significant effect on my particular installation. This is likely because my ADS-B receiver already has a filter in its front end. Your results would be different if using a typical RTL-SDR which would lack any such filtering. Ultimately I returned the filter.

Niet zo best
Niet zo best Er waren enkele punten welke me niet bevielen, het plastieken doosje welk behoorlijk warm werd, geen merkbare aanwinst in contacten, eigenlijk is het best een goedkoop ogend product.

Vraiment très très efficace
Vous pouvez juger par vous meme ... je me suis contenté de remplacer mon filtre 1090 précédent (https://www.amazon.fr/1090-MHz-Passe-bande-aéronautique-passante-Interface/dp/B07D3KRF7H/ref=sr_1_3?__mk_fr_FR=ÅMÅŽÕÑ&keywords=filtre+1090&qid=1583177556&sr=8-3) par celui ci ...

Works okay
Seems to be working alright, I see less bad reading so must be doing something.

安心して使えるADS-B用のフィルタだと思います
AirSpy miniとディスコーンアンテナの組み合わせで使ってみましたがあまり違いはありませんでした。 ついでなのでnanoVNAで特性を測定してみました。 パッシブのSAWバンドパスフィルタのようでオスコネクタ側、メスコネクタ側どちらを入力にしても使えます。電源も必要ありません。 低周波数側の阻止域は通過域に対して-30dB程、通過域の損失は5dB程度あるので低NFのプリアンプと組み合わせて使うのがこのフィルタの性能を活かす使い方でしょうね。 そのうち試してみたいと思います。
