Yaesu G-5500DC Azimuth-Elevation Rotator Systems
Yaesu G-5500DC Azimuth-Elevation Rotator Systems are specially designed to accommodate horizontal cross-booms to mount pairs of VHF and UHF directional antennas for space communications. Providing simultaneous control of 450 degrees of azimuth rotation and 180 degrees of elevation rotation, they are perfect for EME (moon bounce) and satellite communications installations. The G-5500DC dual controller lets you adjust and keep track of both aspects of the antenna system's positioning. The 120 VAC controller includes an interface jack for computer control, supported by the optional GS-232A Computer Controller, as well as many aftermarket control programs and interfaces. These azimuth and elevation rotators are actually two separate motor units, now DC controlled. They may be mounted together on a mast with the included mast bracket, or independently with the azimuth rotator inside a tower and the elevation rotator mounted on the mast above the top of the tower. They handle a total of about 10 sq. ft. of antenna wind load and rotate each way in about one minute. The Yaesu G-5500 AZ-EL clamshell rotator design utilizes 98 heavy 7/16-inch 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. Yaesu's factory-lubricated rotator units are housed in Melamine resin-coated die-cast aluminum intended to provide maintenance-free operation under all climatic conditions. IMPORTANT NOTE: Beginning in 2019 the new Yaesu G-5550DC azimuth and elevation motors operate with two independent 22 V DC control lines, each a five-wire system, using the same connectors at the end of the control cable as the previous models. Both of the new DC motors, azimuth, and elevation, are marked "G-5550DC" at the connector. Be sure to mark your connectors AZ or EL. The rear panel of the controller is titled "G-5500DC" on the serial number label. WARNING: The legacy Yaesu G-5500 Rotator motors and controller used a 26 VAC control voltage, six-wire system. Therefore, old AC controllers are NOT compatible with new DC rotator motors, and new DC controllers are not compatible with old AC rotator motors. All control cable assemblies for all modern Yaesu rotator systems use the same connectors with "1 to 1 pin-out" connector wiring. Therefore, older cable assemblies are compatible with the new Yaesu G-5500DC components, which only use pins 1, 2, 3, 4 and 5 in each connector. For control cable runs less than 125 ft. use five-conductor, 20 gauge control cable (5 x 20 AWG). If the rotator cable needs to be longer than 125 ft. then use five-conductor 18 gauge cable (5 x 18 AWG). The input voltage for the G-5500DC controller is labeled "117 VAC" to indicate house current range of 110 to 120 Vac. When you are launching your EME or satellite communications adventure, an azimuth/elevation combination rotator is a vital tool for your antenna system. As durable as they are attractive, Yaesu G-5500DC Azimuth-Elevation Rotator Systems are available from DX Engineering.

Yaesu G-1000DXA Heavy-Duty Rotator Systems
Yaesu G-1000DXA 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-1000DXA 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-1000DXA 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 23 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-1000DXA, 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-1000DXA Heavy-Duty Rotator System from DX Engineering.

4O3A Rotator Genius Smart Rotator Controllers
4O3A Rotator Genius Smart Rotator Controllers are a high-precision, network-enabled rotator controllers that use a magnetic sensor to read azimuth. They support control via Windows and Android apps and integrate with the 4O3A Genius ecosystem. Typically mounted at the base of a tower in a waterproof housing or installed in the shack, they are compatible with most rotators and control is provided via LAN, USB, or Wi-Fi. A built-in web interface allows multi-user access and full remote operation. Rotator Genius supports independent control of two rotators, making them suitable for stacked arrays or complex installations.
