The Yaesu G-450A is a light to medium-duty antenna rotator, designed for smaller HF beams, tri-banders, or VHF/UHF antennas. It handles a wind load of up to 10 square feet (tower mounted) or 5.4 square feet (mast mounted with optional lower mast bracket). It features a 450-degree azimuth rotation range, with a 360-degree rotation taking approximately 63 seconds at 50Hz and 51 seconds at 60Hz.
Specifications:
General:
- Type: Light-medium duty rotator.

- Braking: Mechanical stopper.
- Operating Temperature: 0 ~ 40 °C (Controller), -20 ~ 40 °C (Rotor).
Torque:
- Rotation Torque: 600 kgf-cm (43 ft-lbs.).
- Braking Torque: 3000 kgf-cm (217 ft-lbs.).
Antenna Considerations:
- K Coefficient: 100.
- Pole-mounted antennas: For pole mounting, the antenna's net weight (including mast) should be 10 kg or less. Additionally, the product of the antenna's wind load area (in m²) and the antenna mast height (in m) should be 0.25 or less according to the manual.
- Tower-mounted antennas: The wind load area can be up to 10 sq. ft.
Note:
The Yaesu G-450A is designed for light to medium-duty applications and has limitations on the size and weight of antennas it can support. Ensure your antenna system's specifications are within the G-450A's capabilities before installation.
