An $80USD filter for $20USD on Amazon..
The reviews look okay. http://www.amazon.com/dp/B010GBQXK8
This should be good of blocking out signals from nearby cell towers,
that might be 'blocking' your 1090 receiver, making it less sensitive.
If your system already has long range, you don't need this kind of hardware.
Since it does insert some loss into your antenna cable.
That's the cost of getting rid of adjacent channel interference.
Looks like a pretty good deal. Might improve SDR rigs, since
it's unlikely they have any build-in filtering.
But, if you live in an interference free area, there's no need for a BP filter.
