Mounting VOR/ILS antenna
Since you are building an RV-7A, you can do exactly what I did as seen on this web page: http://www.n2prise.org/rv9a079.htm There are seven photos to give you the idea.
If you had been building a tail dragger, I would have recommended the sweep of the antenna elements be going AFT, not forward for safety reasons. With the -A models the tail is so high, you will never poke out your eye on the antenna. The aerodynamic drag is the same whether the rods are facing forward or aft. The range for VOR purposes will be slightly better with the rods forward since neither of them would be "shaded" by the vertical stabilizer from reception from the sides of the airplane.
