I can't imagine 3/32 plywood having much effect on RF at that frequency, which is why I put mine inside. Proximity to cables and other steel is apparently not a problem at all for any of the antennas, and I have the radio, transponder, ELT (which admittedly isn't doing anything MOST of the time) and APRS. I don't remember ATC ever complaining about seeing my Mode C. I'd put it inside, again. Come to think of it, that's exactly where I put it in N891JF. Glue a little triangle of 3/32" plywood with a hole in it to the top of a crossmember, and stick the antenna in it. Done, and no holes in the outside of the plane. See enclosed photo...
