Hi All and I'm sure someone has configured GPS this way before. I have an RV6A, Recently installed Dynon Skyview and an IFLY 740 GPS. Both work well. I just installed a Stratux ADSB-in which is configured with an external antenna and when I power up Stratux, I lose GPS signal on both GPS. The IFLY and Stratux both have external antenna. The Stratux indicates all is well with signals and heartbeats. Any idea what is going on? Perhaps to many antennas or to close to each other? Any advice is certainly appreciated. Ed
