Your second message prompts as reply that I am interested in your observation that a non-conductor can make an antenna. Your message is nonsense because the VS is fiberglass with little or no metal in sight, so far as I know.
Even if AF447 plane had an all plastic (non electrical conductive) VS structure it still had an HF antenna in it. And the antenna was not the high current shunt feeder. Itīs more than that and much taller.
Do you know why?
