Model R3500

Heavy Duty Rotator with DRC-4 Rotator Control Unit

The R-3500 Universal Rotator System is designed for medium to heavy duty antenna rotation applications where economy, versatility and reliability are emphasized. Designed for universal applications, the R-3500 will mount in towers with a face width as small as 18”. The high axial load capacity of the rotator makes it suited for top plate mounting on towers.

The output shaft adapter casting will accept any mast shaft diameter from 2” to 3”, and the drive shaft will accept up to 1 5/8” diameter transmission lines concentrically within the drive shaft. The R-3500 is designed for long term regular use under rugged conditions.
