Yaesu G-800DXA Medium Heavy-Duty Rotator Systems
Yaesu G-800DXA Medium Heavy-Duty Rotator Systems are azimuth positioners designed to rotate large tower-mounted amateur and professional antenna arrays under remote control from the station's operating position. These systems feature attractive compass-dial position indication controllers, with a connector port for optional computer interface for automated directional antenna positioning control. Yaesu's G-800DXA rotator design utilizes 98 heavy 3/8 in. dual-stacked circumferential ball bearings to distribute load over the full diameter of the housing. This design minimizes stress and wear and practically eliminates the possibility of destructive water entry: There is no shaft hole in the top of the housing. Instead of the usual AC motor drive used in older rotator designs, the G-800DXA use a variable-voltage DC motor, removing the need for a large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. A mast alignment gauge on the rotator housing simplifies accurate mechanical alignment during installation. Tower mounted, this model handles over 20 sq. ft. of antenna wind load and over 400 lbs. of vertical mast load. Installation is required for included plug connectors on to the installer supplied 6-conductor control cable; 20 AWG for lengths less than 125 ft. and 18 AWG over 125 ft. Console power is 117 volts AC for units sold in the USA. The handsome desktop controller provides 360 degrees radial indication of actual antenna azimuth bearing. You can select rotation time over 360 degrees from 40 to 100 seconds on the G-800DXA, and preset a desired heading for the rotator, to which it then turns automatically. The operator may select the stop heading, the compass bearing through which the rotator cannot be turned, which is most convenient for their station location and operation, allowing full rotation through north, south or both, if desired. In any case, 90 degrees overlapping rotation allows rotation through the selected stop heading for 450 degrees of total rotation. These rotators are intended for mounting to an accessory shelf inside a support tower (not supplied), at least 1-meter (40 in.) below the top of the tower. Yaesu rotators have a fine reputation within the Amateur Radio community. When installing a new tower, or replacing an old rotator, consider purchasing a Yaesu G-800DXA Medium Heavy-Duty Rotator System from DX Engineering.

Yaesu Rotator Computer Controllers
Yaesu Rotator Computer Controllers are interface devices that link your Yaesu Rotator Controller to your computer via RS-232 (COM) connection. These units include the interface cables for the connections to the rotator controller and a PC serial port. Yaesu Rotators that support this computer interface are models G-2800DXA/DXC, G-10000DXA/DXC, G-800DXA and G-5500 rotators. Automation of directional antenna positioning is possible with Yaesu Rotator Computer Controllers.

Yaesu AAA67X021 Replacement Rotator Controllers
Yaesu AAA67X021 Replacement Rotator Controllers keep your antenna turning after controller failure. These controllers are direct replacements for the G-2800DXA, G-1000DXA or G-800DXA rotator systems. These replacement desktop controllers feature a 360 degree radial indication of the actual antenna bearing azimuth. These modern DC controllers support the selection of rotating speeds from 40 to 100 seconds per rotation (360 degrees) for either the G-800DXA or G-1000DXA, or 50 to 120 seconds per rotation (360 degrees) for the G-2800DXA, and can preset a desired heading for the rotator, to which it then turns automatically. With the G-2800DXA, when a fast rotating speed is selected, special "auto slow-start" and "auto slow-stop" features avoid sharp jolts to the antenna array and tower. Activating the rotator causes it to begin turning at slow, but increasing, speed. As the antenna approaches the desired heading, the rotation automatically slows down, before bringing the antenna to a gentle stop. The operator may select the end-of-rotation heading (the compass bearing through which the rotator cannot be turned) most convenient for his location and operation, allowing full rotation through north, south, or both, if desired. In any case, 90 degrees of overlapping rotation allows rotation through the selected stopper heading (450 degrees total rotation). Need a replacement controller for your Yaesu rotator?
