I’ve searched to no avail, Just added the ADS-b filter made by flightaware. I have the Pro Stick as well. Once added I went from 35 current planes being to tracked to just 1. Still using a tuned stock mini antenna. Worked fine for me so far. I was getting 50-100 ish miles
Stock Antenna placed outside cut to tune as told on here
Lost my planes
I tried looking for info on how to set the gain and tried several ones but ended up now with no planes being tracked. SOOOOooo.
Update**Took Filter out and started tracking more planes…
