Extended Satellite Reach
Early antenna designs often incorporated expensive anti-backlash configurations, but Scientific-Atlanta was looking for less expensive solution that would provide even better positioning results. Scientific-Atlanta uses large satellite communication earth station antennas as international gateways for voice and data communications. Their 18-meter antenna required precise positioning to within 0.01 degree in the elevation and azimuth axes. They needed a worm gear screw jack that would provide this level of precise positioning, even in extreme environments.
Nook's 75-ton ActionJacTM worm gear screw jacks were the solution Scientific-Atlanta needed. 75-ton jackscrews provide precise positioning, even in extreme Arctic environments. In addition, they provide the structural integrity needed for hurricane-force wind survival conditions.
