The Yaesu G-1000DXC is a professional-grade antenna rotator system engineered to manage and position large tower-mounted amateur and commercial HF and VHF/UHF directional arrays under precise remote control from the operating position. Built for demanding DXers, contest stations, and critical communication links, it provides smooth, quiet, and reliable azimuth alignment across all operational conditions.
Its robust clamshell housing incorporates 98 dual-stacked 3/8-inch circumferential ball bearings that evenly distribute axial loads and torsional stress across the entire diameter of the melamine resin-coated die-cast aluminium casing. This clever mechanical geometry features no shaft hole in the top of the housing, drastically minimising stress and virtually eliminating any risk of water ingress. Driven by a variable-voltage direct-current (DC) motor, it eliminates the need for external starting capacitors that tend to degrade with severe temperature shifts. The system includes a desktop controller featuring a 360° radial compass scale with 90° overlap (450° total rotation), automatic PRESET positioning, and a dedicated rear Mini-DIN interface for PC control.
Key Advantages
- Engineered for Large Arrays (K-Factor = 230): Accommodates directional antennas with a wind loading area up to 2.2 m² in tower installations, supporting continuous vertical loads of 200 kg (with a momentary peak load of 800 kg).
- Intelligent PRESET Controller: Enables operators to dial in the target azimuth heading and momentarily press the START switch for automatic, hands-free rotation and stopping.
- 98 Circumferential 3/8″ Bearings: Dual-stacked bearing tracks distribute vertical weight across the housing without a top shaft opening for superior weatherproofing.
- Heavy-Duty Mechanical Brake (6000 Kgf-cm): Firmly secures large booms against intense wind gusts, backed by 1100 to 600 Kgf-cm of rotational torque.
- Extended 450° Azimuth Range: Full 360° rotation plus a 90° overlap sector with a dedicated OVERLAP LED indicator to avoid unnecessary reverse rotations.
- Computer Automation Ready: Equipped with a 6-pin mini-DIN EXT CONTROL socket on the rear panel, directly compatible with the optional Yaesu GS-232B PC interface unit.

Frequently Asked Questions
How many cable conductors are required to wire the system?
Although the supplied plugs feature 6 and 7 pins respectively, the G-1000DXC wiring only requires a 5-conductor control cable (the remaining pins are unused). For runs up to 40 metres, conductors of at least 0.5 mm² (#20 AWG) are recommended; for runs exceeding 40 metres, use 0.75 mm² (#18 AWG) conductors.
Can this rotator be controlled via logging or contest software on a PC?
Yes. The controller features a 6-pin mini-DIN EXT CONTROL socket on the rear panel. Connecting the optional Yaesu GS-232B interface unit enables automated bearing tracking and control via RS-232 serial commands from software suites like N1MM, Log4OM, Ham Radio Deluxe, or PSTrotator.
Is it necessary to drill a hole through the antenna mast?
Yes. The installation instructions require drilling a 9 mm transverse hole 50 mm from the bottom of the mast to fit the supplied M8 x 95 mm through-bolt and square nut. This mechanically locks the mast to prevent twisting or slipping under severe wind loads.
