I'm installing a Garmin G3X touch in my RV8. I have a GTX 335 transponder and I have a GA 35 antenna which is compatible according to the installation manual. The GDU 460 also requires a GPS antenna and I was hoping to use the same antenna however the installation manual states that the GA 35 cannot be used. Whilst not an authority, I note that the Aircraft Spruce website recommends the GA 35 antenna for use with the GDU 460. Do I need to run two antennas? If so, does anybody have any recommendations as to what would work best with the GDU 460? Thanks in advance for any help.
