Automatic Antenna Polarization Switching Device

Key Features

･Low Electromagnetic Interference Design: Utilizes resin materials and a compact design to minimize the impact of electromagnetic wave reflection.
･High Precision Positioning: Polarization switching accuracy of ±0.3°.
･Conditions: Antenna positioned within 1m of the pole center, at the center of rotation, and antenna mass of 7kg or less.
･Fast Operation: Antenna polarization switching time is approximately 6 seconds.
･Capacity: Supports antenna loads up to 7kg.
･Portable & User-Friendly: Lightweight design equipped with casters for easy transport and movement.
･Advanced Control: Supports GPIB control and uses optical fiber cables for signal transmission.
･Adjustable Height: Manual height adjustment (200mm range with 25mm pitch).
･Customization: Optional adapters for various antenna types are available. A 1.0m height version can be manufactured upon special request.
