When I run my antennas out the bottom, I hook them to the tailwheel. First of all, I always tie a knot in my antennas about three or four inches from the rx to keep them from pulling out of my receiver. Then I drill a 1/16" hole in my fuse and stick out the antenna. The I reach it back towards the tailwheel, and grab it about four inches short of the tail wheel and tie a rubber band onto it there and hook it over the tailwheel (the rubber band that is). Then just let the extra hang out. Be careful not to step on the antenna!@#&@%#&*!@
