Bypass the rotor with thick ground lead from the rotating pipe mast to the tower, use ceramic bypass capacitors on the pot contacts and MOVs or low voltage spark gaps to ground on all lines to the rotor and controller. Use screened rotor cable, with the screen grounded to the tower at top and bottom.
