Band Pass Signal Filter, Dual 978-1090 MHz

Helps filter nosie out as have lots of wifi and other signals nearby.

As advertised!

I purchased this to knock out any front-end overload on my rx and the first thing I did was sweep it with my service monitor and it looks great just as advertised it drops off sharp below about 970mhz to around -55db and above around 1100ishmhz again around-55db of reject and the pass looks really flat in-between those two frequencies at -1.4 to -1.8 db of insertion loss, not bad for a filter.

Added filter to improve ADS-B reception

Added this filter to an external antenna (12dBi gain omni) and it seems to have improved the performance of my receiver (along with dynamic gain adjustments). So far, so good.
