I picked up a couple of facia board TV antenna mounts and made the mount for my system at the peak of my roof. It’s at the peak or a 2 story home, and wind speed/direction is accurate according to CWOP (Citizens Weather Observer Program).
I can tell you from personal experience - my Ambient 1090 would struggle to hold a reliable connection from that same mount to my office in the basement and the computer connected to a console and running my weather software.
It’s not so much the distance as it is the drywall the signal has to penetrate.
Once I went to the Davis Vantage Vue, all problems ceased.
