Correct, power amplified antenna. I have no clue how they work, to be honest. Yes you can unpower it, theres a connection in the rear of the cd deck that powers it. When i first installed my cd player i forgot to hook that up and got crappy reception, but i did get SOME reception.
What do you mean it doesnt work at all NiSlo? Does it work at all with no antenna hooked up at all? It doesn't make sense that it wouldn't at all, even if bad reception. (i think i used 'at all' a few too many times)
