If you don't understand the numbers, what that means is this thing knocks out the interference from nearby cell towers so your SDR can hear the ADS-B signals from local (and not so local) aircraft.
A good friend with a very close cell tower is seeing very good increases in the number of aircraft and aircraft range with a popular ADS-B software package and this filter.
This is a very good filter for ADS-B at a very reasonable price!
That said, it would be better to have a narrow filter with about 5MHz bandpass at 1090 and a separate narrow filter with 5MHz bandpass at 978. Why? Well, the SDR's have no front-end filtering and with a bandwidth of 943 to 1183MHz everything in that range is presented to the SDR device including transponder outputs and all kinds of other aviation related signals we don't care about which can overload the input of the SDR.
Even though it's a very wide-band filter and I'd prefer to have a more narrow 1090MHz specific filter, I give it five stars because the build quality is good, it works better than anything else available in this price range, and it's an amazing value. Until I find some narrow 978 and 1090 specific filters this is what I recommend.
Placement is as follows: ANT - THIS FILTER - AMP - RECEIVER
UPDATE: This filter has died. Far to early & out of warranty/return eligibility. It worked so well for awhile but I can't afford to replace this filter every other or every few months.
UPDATE: After trying to get this resolved (see comments) I gave up. I tried again here towards the end of July. I got to talk to people! In a nutshell, it was my fault it died. I didn't realize that these are NOT WATERPROOF - I was using mine outside on the antenna's mast. Even so, they wanted to send me a replacement. It just arrived & I wanted to update my review. So, do not place these filters outside without some sort of WATERPROOF protection! TYVM FlightAware!
