You won't need another rotor and for the price I'm selling you'll be sorry if you don't purchase it. Retails over $2000.00 I did paint it black from its original grey. Looks better in my opinion. Comes with original box, manual, connectors, hardware and works perfect. Asking: $1000.00 N2RRAny@aol.com M2 Antenna Systems, inc. builds one of the best rotator systems.
