ERC-51 & ERC-51D :- These 2 models of elevation rotators are designed for light weight to medium size Satellite or EME antenna systems. With easy U-bolt installation & cost effectiveness. Employing a worm drive system into two stage reduction gearing, driven by a high torque 28v AC motor for the ERC-51 model, where as the ERC-51D is driven via a 12v DC motor. They have low backlash with high rotation torque, powerfully braking without relying on any auxiliary brake system. With a total of 4 gears, two made from high tensile steel (running in a grease filled chamber) where as the other two gears are made from zinc alloy, all gears running on separate shaft. They come standard with Dial Pre-Set & Speed controls including computer interface.

ERC-5A :- This model elevation rotator is designed for large EME antenna or parabolic dish systems. Employing a worm drive system into two stage reduction gearing, driven by a high torque 28v AC motor. With high rotation & brake torque of the worm drive & reduction gearing via chain drive making it well suited to these large antennas. The four internal gears are made of high tensile steel (the first two gears run in a grease filled chamber & with all gears running on separate shafts) which then drives the anti-corrosion high tensile steel chains. Comes standard with Dial Pre-Set & Speed controls including computer control interface.
