monitoring the traffic on my tablet, ATC had been reporting each of us

Can anyone say if a Trig TT22 with TN70 will provide collision warnings?


The TT22 and TN70 gives you ADS-B Out only, unlike your GTX-345 that does ADS-B Out/In (1090ES Out and 1090ES In and UAT In). Glider pilots would normally get ADS-B In via a PowerFLARM (1090ES In only) or if they have room for a separate display then in some cases a Stratus or Stratux receiver (and if you do that get a dual link receiver).
