Spent time figuring on the location of the dipold ILS/VOR/LOC antenna. I referenced photos of my friend Rick's RV8 to get a general idea of where he placed his. The antenna I bought is a little different but fairly close to the same.
I surveyed and marked a location on the belly. Next I got a piece of .040 aluminum sheet and began designing the doubler. My point is if your going to make a doubler....make a stout one!
