Know before you buy
Yes, the G-5500DC features two independent DC motor units. While they are designed to be mounted together using the included mast bracket for satellite tracking, they can also be installed separately depending on your specific tower or mast configuration.
The system requires two separate 5-conductor cable runs to connect the controller to the azimuth and elevation units. Ensure you have sufficient length for your specific cable run from the shack to the antenna installation.
Yes, the controller includes a built-in computer interface, allowing it to integrate with most popular satellite tracking software. This enables automated antenna positioning for EME and satellite communications.
The clamshell design, reinforced by 98 heavy-duty ball bearings, helps distribute mechanical stress more evenly across the housing. This construction, combined with the Melamine resin-coated die-cast aluminum, provides excellent weather resistance and durability for long-term outdoor use.
The elevation unit is designed to accommodate a cross-boom with a maximum outside diameter of 1.675 inches. Please verify your antenna boom size before installation to ensure a proper fit.
No, the G-5500DC is designed for maintenance-free operation. The housing is sealed and coated to withstand various climates, so you do not need to perform routine lubrication on the motor units.
