If you do decide to run the antenna through a tube inside the fuselage, you must do two things: 1. Put a strain relief to prevent any strain on the antenna at the receiver. 2. Make sure you put something on the end of the antenna wire right at the end of the tube to prevent the antenna from snaking back into the fuselage due to vibration. A little dab of hot glue will do just fine and you can remove it if you have to.

That can and does happen. If it does ha.ppen, you will end up with a ball of an antenna at the inside end of that tube, all jumbled up and tangled, which will make the antenna pretty much useless.
