The antenna body or if present a small wire out of the motor lead is ground. The motor has two separate oppositely wound field coils tied together at one side of armature, other side of armature to case ground. Only one of the lead wires used at a time--one is up, the other down. The center of up/down switch connects to the circuit breaker.

From what I can see, maybe 2' of the nylon has broken off. The usual failure, aside from broken mast is for various reasons the mast sticks but motor keeps turning and either breaks or wears a spot in the nylon. Once the worn spot hits the drive rollers, it rarely goes any further & just gets worse.

New repro mast assys were or are available for a price from some of the vendors, but have not been able to find just the nylon for either style antenna
