I don't know about the jet guys, but I use the whip antennas when I can't get a full length antenna run in my fuselage. So the antenna is hidden inside all my planes. Larger fuselages I have a red NyRod tube built in and just run the regular wire antenna up through it. Shorter fuselages I install a Deans antenna. Looks nicer and nothing external to damage. Ever seen someone step on a dangling antenna wire and rip it out? I have!
