The "tank" output transformers used in radio transmitters use the same sort of thing and can have "tons" of bandwidth; You'd need to prevent transmitting your TV / VGA signal all over the place in undesired bands, lest the FCC come looking for you, of course. And you'd still need to use coax from the pickup to the HUD anyways to preserve signal quality - so: Biggest question I have is, what would induction get you that you want? You lose the ability to transfer power from belt battery pack to the HUD, so now your batteries are on the HUD and your neck's getting shorted by the second; You still have a cable from where the NTSC signal's generated to your HUD, you're losing not gaining in my views <G> Might be able to get away with using a short-range RF link to pass the NTSC signal from wearable to HUD to get rid of that coax link; Still have that pesky battery pack weighing the HUD down, low battery life on the HUD end of things, etc., now, though. (I thought the purpose of those induction pickups was to allow people with hearing loss to hear radios, cassette players, etc. without trying to put a headphone on over their hearing aid? I'm no expert on hearing aids.)
