    The antenna he showed is very similar to what I put inside my fuselage right behind the baggage compartment. Curved around the inside of the fuselage that way, it has both a vertical and horizontal component, regardless of how the fuselage may end up following an "incident"! Believe me, that antenna will work, and it will work quite well! To get the best performance, put a clamp-on ferrite on the coax close up to the antenna feed-point, and, as you should always do whenever possible with ANY antenna, bring the coax away from the antenna perpendicular to the antenna axis to minimize antenna currents. That's a much, much better antennna than a rubber-duckie, which you will find can receive a signal on a hand-held over quite a distance! Look at the little antenna they supply with the ELT to be used with the unit as a hand-held. If that works, the inside antenna will work!
