i dont have one, but i would guess the magnetic contacts are just that. and probably when next to each other, complete the circuit that says the antenna is either down or still not all the way down. like magnetic window alarm system ones.

does it go up and down and also rotate? if so, then there is just two motors. dc motors are simple. one polarity goes one way and the other polarity goes the other way
