Daniel" : Hi again guys, Can someone tell me if a GPS in a glass airplane needs a ground plane? I have 2 GPS antennas mounted in my ES that seem to work fine without ground planes. I am about to make some changes with these and will add a ground plane if necessary. Thanks for you input. Chat Daniel Super ES N891AC
