Installed main GPS antenna for G430W at top of canopy. My old radio shop (Betts at Spark Chasers) emphasized following good practices in locating and installing these antenna.
Two other GPS antennas for GRT/HX system and TruTrak ADI are installed on small shelves that will be under windsheild.
Used mini-overhead console from Dave Saylor to cover cabling and later, to mount swiveling red map lights from Stein
