I just added the band filter to my ADS-B receiver, holy crap I'm getting even more planes now. Not necessarily more range, just more planes. I wanted to try without the filter before just to get an idea of performance so I can determine if it's better with or without it, but it seems to be better with it. I can't wait to put this antenna outside higher up in summer to see how much further I actually pick stuff up.
Just glad my ISP has unlimited bandwidth... I'm at like 1MB/sec upload right now feeding all this data to the tracking sites lol.
