And this is what the "servo horn" piece looks like.
By the way, I've changed my method of attaching to the stab. I now use a short piece of fuel tubing with two (or four) slits cut half way through. Thread the antenna into one end, out the first slit, back in the second, and so on. Then use the same "pin" method to connect to the stab.
The tubing seems to hold up better than the rubber bands, but in a crash the antenna will still pull out of the tubing saving the antenna.
I still use an old horn as a strain relief inside the fuse though.
