I currently have FreeFlight 1201 as a GPS source connected to Trig T22. I also have a couple of "experimental" GPS sources driving other instruments.
I find the non-TSO GPS sources working perfectly in a wooden hangar while the FreeFlight 1201 is not able to obtain a lock, or at least there is no position displayed on T22. The other instruments work just fine. Of course the FreeFlight 1201 works just fine outside, but I had a difficult time finding a place for an antenna that would not cause reception problems.
FreeFlight 1201 being an old design probably has low sensitivity GPS receiver. Does anyone have experience with Garmin 20A and is able to obtain position in a garage or a wooden hangar? I presume that Trig will only display position if the quality of signal is acceptable and that might be the reason for the difference in performance.
Thank you in advance,
Andrzej
