The plans on page 26-10 call for drilling two 11/16" holes in the bottom skins of the fuselage (one on each side). But, like the call out for drilling a large hole in the bottom of the aft fuselage, they don't mention what these holes are used for (at least not on page 26-10). In the case of the large hole in the aft fuselage, I learned that hole is used for an ADSB antenna which I don't need because I'm using a Garmin GNX-375 which I understand uses the GA-35 antenna which includes both GPS and ADSB. I think.
Before I drill two more large holes in the bottom skins that I don't need, does anybody know what these two holes in the mid fuselage are used for? I'm assuming it's for antennas but if so, how does Vans know which antennas people use or where they want them installed (or how big the holes should be)? Sorry for the stupid question but I'm a clueless new builder.
I've purchased two antennas from Stein. The Comant CI-122 COM antenna and a Garmin GA-35 GPS antenna. I don't plan to navigate using VOR so no VOR antenna. I figured the COM antenna would go on the bottom of the fuselage and the GPS antenna on top somewhere. I also assumed I'd be mounting these antennas later in the build when I'm doing the avionics.
If these two holes are used for antennas, it seems to me the plans should say - "If you plan to mount a COM antenna on the bottom of the fuselage, drill an 11/16" hole here. If you plan to mount a VOR antenna, drill an 11/16" hole here."
