And a prostick+ i assume?

If you are in Europe, a dark blue SMA filter might fare better.

Actually with that nasty interference near 1066 MHz, i’d personally try a SAW filter:  
[https://www.amazon.de/AirNav-RadarBox-1090-ADS-B-Filter/dp/B082WR1SDF](https://www.amazon.de/AirNav-RadarBox-1090-ADS-B-Filter/dp/B082WR1SDF)

There are other makes.  
SAW filters have sharper cutoffs and a narrower bandpass than the LC filters from flightaware.  
(and the dark blue FA filter is much narrower than the very wide light blue FA filter)
