The Yaesu G-800DXA Medium-Duty Rotator System is engineered to provide precise and reliable azimuth positioning for large, tower-mounted amateur and professional antenna arrays. Designed for seamless remote control from your station's operating position, this rotator system ensures optimal antenna orientation for enhanced communication performance.

Robust Rotator Design

At the heart of the G-800DXA is a meticulously crafted rotator unit featuring 98 heavy-duty 3/8-inch dual-stacked circumferential ball bearings. This design evenly distributes the load across the full diameter of the housing, minimizing stress and wear. Notably, the housing is engineered without a shaft hole at the top, effectively eliminating the risk of water ingress and enhancing the system's durability.

Advanced Motor Technology

Departing from traditional AC motor drives, the G-800DXA utilizes a variable-voltage DC motor. This innovation removes the need for a large starting capacitor, which can be prone to failure due to temperature variations. The DC motor ensures smooth and reliable rotation, enhancing the longevity and performance of the system.

Comprehensive Rotation Control

The G-800DXA offers a full 360 degrees of rotation with an additional 90 degrees of overlapping rotation, allowing for a total of 450 degrees of movement. This feature enables the antenna to rotate beyond the standard range, providing flexibility in antenna positioning. Users can select the rotation time over 360 degrees, adjustable between 40 to 100 seconds, catering to specific operational needs.

User-Friendly Controller Interface

The accompanying desktop controller is designed with an intuitive compass-dial position indicator, providing real-time visualization of the antenna's azimuth bearing. For enhanced automation, the controller includes a connector port compatible with an optional computer interface, facilitating automated directional antenna positioning control. Operators can preset desired headings, and the rotator will automatically adjust to the specified direction. Additionally, the controller allows selection of the stop heading, enabling full rotation through north, south, or both, as per the station's requirements.

Installation and Mounting Specifications

The G-800DXA is designed for installation on an accessory shelf inside a support tower, positioned at least 1 meter (40 inches) below the tower's top. This placement ensures optimal performance and longevity of the system. The rotator is intended for mounting to a rotator mounting plate within the tower structure, providing a secure and stable setup for large antenna arrays.
