Yaesu G-450ADC Medium-Duty Rotator Systems
Yaesu G-450ADC Medium-Duty Rotator Systems are the entry-level rotator and controller that are perfect for small HF beams, a tri-bander or VHF and UHF antennas up to about 10 sq. ft. of tower-mounted wind load. A lesser wind load of about 5 sq. ft. can be handled when mounting the G-450ADC on top of a mast with the optional lower mast bracket, GC-038. Rotate Amateur and professional antennas with the Yaesu's handsome 120 Vac desktop remote control console, featuring a compass-style indicator at the station operating position. The G-450ADC rotator system provides 450 degrees of azimuth rotation in just over one minute. The rotator handles masts of 1.25 to 2.48 in. outside diameter and, when tower mounted, a total vertical mast load up to 200 lbs. In the Yaesu G-450ADC, the 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-450ADC Rotator motors and controllers operate with a 20 V DC control voltage, four-wire system, using the provided connectors to be installed at each end of the user supplied control cable, same as the previous models. For clarity, the new DC rotator motors are marked "G-450DC" at the connector. The rear panel of the controller is titled "G-450ADC" on the serial number label. WARNING: The legacy Yaesu G-450A Rotator motors and controllers used a 26 VAC control voltage, five-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-450ADC components, which only use pins 2, 3, 4 and 5 in each connector. For control cable runs less than 125 ft. use four-conductor, 20 gauge control cable (4 x 20 AWG). If the rotator cable needs to be longer than 125 ft., then use four-conductor 18 gauge cable (4 x 18 AWG). The input voltage for the G-450ADC controller is labeled "117 VAC" to indicate house current of 110 to 120 Vac. When you need a medium-duty rotator system, which is durable and attractive, order a new Yaesu G-450ADC Medium-Duty Rotator System from DX Engineering.
