The Yaesu G-450CDC is a professional azimuth antenna rotator system engineered to deliver precision tracking control, structural stability, and reliable long-term operation for compact communication station antenna arrays. Manufactured to strict architectural tolerances, this high-performance rotor is an ideal choice for municipal emergency communication towers, directional VHF/UHF tactical links, satellite telemetry arrays, and compact HF tri-band directional beams. Designed to seamlessly manage base station rotation workflows, it enables operators to target and orient directional antenna elements precisely along a complete 360-degree trajectory.
Built to endure the most demanding environmental exposure, the G-450CDC features a ruggedized housing forged from a heavy-duty aluminum alloy. The entire mechanical envelope is completely waterproofed and treated with a specialized lubrication-resistant compound that keeps moving gears fully operational for years without oil degradation or performance loss. Exterior chassis treatments, powder coatings, and electrical connection blocks are custom-engineered to withstand severe weather, including torrential rain, freezing ice storms, marine salt spray, and extreme solar radiation. At the core of its mechanical architecture is a proprietary planetary-type braking system that provides an exceptional brake torque of 3,000 kg/cm. This highly efficient design eliminates backlash and false mechanical shifting while maintaining quiet, smooth, and vibration-free positioning cycles.
The mechanical performance metrics of the Yaesu G-450CDC ensure versatile antenna matching capabilities. It supports a maximum continuous vertical load of 100 kg, an instantaneous maximum point vertical load of 300 kg, and can comfortably manage antenna arrays presenting a wind resistance profile up to 1 m². With a robust starting torque of 600 kg/cm, the rotor achieves a full 360° azimuth sweeps in an efficient 63 seconds. The heavy-duty mast clamping brackets accommodate standard support poles ranging from 32 to 63 mm in diameter. Housed in a balanced 170 mm diameter x 263 mm structure and weighing 3.2 kg, this azimuth rotor delivers premium structural performance engineered for absolute year-round field dependability.
Important Operational Note: The Yaesu G-450CDC requires a 6-wire control cable installation to interconnect the rotor unit with your station controller. Please note that the connection cable and terminal interface connectors are NOT included in the standard factory package and must be sourced separately according to your station layout length requirements.
Key Features
- Weatherproof Aluminum Casing: Die-cast aluminum alloy chassis provides structural strength while completely sealing out rainwater, blowing dust, and moisture.
- Planetary Braking Architecture: High-performance internal planetary brake locks the antenna array firmly in position with 3,000 kg/cm of torque, preventing wind-driven backlash.
- Lubrication-Resistant Sealant: Factory-treated with advanced internal lubricants engineered to resist break-down or weeping under high thermal or physical loads.
- Quiet & Smooth Sweep Profile: Advanced internal gear train provides highly precise, quiet operation, completing a full 360-degree rotation cycle in 63 seconds.
- High Structural Load Limits: Manages continuous vertical loads up to 100 kg (300 kg instantaneous peak vertical load) and up to 1 m² of total wind surface area exposure.
- Versatile Mast Accommodations: Heavy-gauge mounting clamps securely grip standard structural antenna masts ranging from 32 mm to 63 mm.
