Antenna Rotator Systems

Weather can be unpredictable, especially due to global warming. To ensure reliable communications with other devices, it is important to use a weatherproof antenna rotator system. Antenna rotators are motorised units that can help you get better reception from different directions. These systems are designed to withstand the harshest weather conditions, so you can stay connected no matter what comes your way. 

Components of Antenna Rotators

Antenna rotators consist of several components, including:

  • Rotor Unit: The rotor unit is the central component of an antenna rotator and is responsible for physically rotating the antenna. It is typically mounted on a mast or tower and attached to the antenna.
  • Control Box: The control box is the component that controls the rotation of the rotor unit. It contains a motor, gears, and other mechanical components that work together to rotate the antenna. The control box also contains the electronics that allow the user to remotely control the rotation of the antenna.
  • Drive Unit: The drive unit is the component that provides power to the rotor unit. It typically consists of a motor and gear train that transmits the rotational force from the control box to the rotor unit.
  • Control Cables: The control cables are the wires that connect the control box to the rotor unit. They carry the electrical signals that control the rotation of the antenna.
  • Mast Mount: The mast mount is the component that attaches the rotor unit to the mast or tower. It is important to use a strong and stable mount to ensure that the antenna can rotate smoothly and withstand wind and other environmental conditions.

Finding the Right Antenna Rotator System

When it comes to installing your antenna rotator system, it is important to be aware of the rotator’s turning and braking capabilities. Rotator failure occurs when the rotator is too small for the application, causing damage to its gears during storms. This typically happens when the rotator’s turning and braking capabilities are under-specified. That’s why it’s important to ensure the rotator’s turning capability is sufficient.

To determine the turning and braking capability, calculate the K-Factor, where K = Turning Radius x Weight of Antenna. Calculator the K-Factor (in Foot Pounds) for each antenna and add the K-Factors together. Next, compare both the K-Factor and the Surface Area (in Square Feet) of your antenna(s) to the specifications. The rotator is safe if both are within the ratings.

Frequently Asked Questions about Antenna Rotators

An antenna rotator system is a device used to remotely rotate an antenna to different angles, allowing for optimal orientation and reception of signals from various directions. Simply put, antenna rotators provide a convenient way to adjust the antenna direction, ensuring clear and strong signals.

An antenna rotator is controlled by a motor to achieve the best orientation for receiving signals from a desired direction. The rotator typically consists of a motor, gear system, control unit, and the antenna itself. The control unit sends signals to the motor, which rotates the antenna to the desired angle.
