I was advised by Stein Friday that the 2020 compliant GPS receiver requires a separate antenna from the GA26C they sold me that only works for the G3X460 screen. There is no glare shield real estate in an RV4 to place them. Some folks put them successfully FWF under fiberglass cowl. The plugs on these antennas are large relative to wires, so passthroughs to rearward areas near the roll bar could get ugly.
My question for the more experienced than me is:
1- A area in the fuse avionics cover could have a window in it to mount antennas with a sky view, cool temps, simple routing. What is best to make it from?
A-Fiberglass is proven workable, but may not be optimum.
B- Can the fiberglass be painted with the aluminum "boot cowl" that it is built into ?
C- Plexiglass could be mounted as a window. More difficult to mount, could craze.
Does anyone know how much performance is lost relative to air, for plexiglass, fiberglass and painted fiberglass ?
