Sooner or later, they will cut Everything off. There is no safe place for the antenna, and the harder you work to hide it, the harder the props will work to find it.

Personally, I just run the antenna out of the fuse (or along it for profile planes), then out to the tip of the vertical stab, then down inside the coro stab and out the bottom to trail along after the plane. I ususally loosely tape it with a couple of tabs of packing tape. I figure that if a prop hits it, the antenna isn't attached very well to anything, and can be moved out of the way by the prop rather than torn from the receiver. I usually use some strain relief near the rx as well.

I have had a couple of antennas cut, but I don't sweat it. They were both FMA rxs, and if you check with the FMA website, they say you can cut the antenna fairly short. Just do a range check to make sure everything is working ok.
