I just drill a small hole, right about mid ship, in the bottom of the fuse. Sorta right under the canopy area. I thread the anteana through the hole and extend it towards the tail. I take a small piece of a servo are and thread it through that and let it come up against the inside of the fuse so it doesn't put pressure on the receiver where the wire enters. I do the same thing on the other end and use a rubber band around the end one and then loop it around the tail wheel. Makes a clean installation and it's hidden pretty well. The only drawback is the receiver won't pick up and of the radio commands.
Thanks,
Barry
