If I may butt in here. I keep my antenna inside the fuselage. The reciever is usually placed in the middle of the wing saddle. There is about 6-7 inches of antenna going forward, in a piece of plastic tubing, to the firewall. The antenna then loops back to the rear of the fuselage, taped to the inside. There is about one inch sticking out the back which is taped to the rear outside fuselage.
