Just for grins I picked up one of these cheap GPS antennas that stated it was compatible to the Garmin GA 26C antenna. https://www.amazon.com/Xtenzi-Exter...=1-1-catcorr&keywords=Xtenzi-External-Antenna Under $20 and shipped free. On the RV-10 I had a triple screen legacy G3X and I used the Garmin GPS antennas. The RV-9A is also a G3X panel, except the pilot side has a GDU 475 Touch, and the co-pilot side has a stand alone G3X legacy GDU 370 system. I wanted the co-pilot side to be a stand alone system for a back-up PFD instead of a G5. So I tested this new antenna on the GDU 370 today to check it out. No reception inside the hanger but I couldn't get any on the RV-10 either inside. I cracked open the door and pulled the new antenna outside about 3 feet from the hanger on the ground and it locked on. (cloudy day) One thing it did was lose a couple satellites an d lock back on seconds later. I don't recall if my RV-10 with the Garmin antennas did this. Any way, here are some screen shots of the satellite receptions. Thoughts? Go or no go with this antenna? Thanks for any input.
