On the Venture, I took the antenna and routed it out the bottom of the fuselage, covering it with the same black ultracoat I covered the bottom in. About 1 in. sticks out the back at the rudder.

On the Astro Hog, the antenna exits at the rear of the canopy, and there is a pin that captures the antenna wire inside a short piece of tubing at the top of the vertical stab.
