The buzzing sound was vortexes shedding on alternate sides of the winglet. You'll see that in some of the other videos. Think: Tacoma Narrows Bridge.

Make a fin of solid foam so the sides don't flex, and put the antenna at 30% of the chord, instead of clear at the front. That will give any vortexes less leverage.
