Analysis of The Current Status of Low-Orbit Satellites (LEO)
On behalf of Antesky, one of our European clients ordered 1.8m Carbon fiber C-band flyaway antenna this month. We had assembled and tested this 1.8m flyaway manual dish antenna before shipping, which is the must step for testing every batch before leaving our factory to assure 1.8m portable antenna delivered to customer in good performance and quality. Below is the package and testing details for your reference.

The radiation pattern of AZ and EL for 1.8m flyaway manual dish antenna
The components of Antesky manual portable flyaway antenna are mainly included panels, support bracket, feed, OMT and AZ/EL adjustment mechanism.The feed is installed on the Focal point of antenna panel; the duplexer is on the feed , the feed is fixed to the antenna panel through a support rod; the EL adjustment device is installed on the rear of the antenna panel, and the azimuth adjustment device is mounted on the bracket, the antenna panel is mounted on the azimuth adjustment device, and the horizontal device is on the azimuth adjustment device.
When satellite communication is required, firstly determine whether the ground is level by using a horizontal device, adjust the azimuth adjustment device and elevation adjustment device to aligning. After satellite alignment and satellite communication is completed, the reclining operation can be adjusted by adjusting the azimuth adjustment device and the elevation adjustment device which adopts mechanical structure for adjustment, simple operation, high adjustment accuracy, light structure and long service life.
In additional, due to Antesky carbon fiber portable flyaway antenna’s high integration and light weight, it is packed in a portable box and made of high-strength materials, which can effectively protect the transportation safety of the equipment and is suitable for vehicle, airborne, and other transportation modes.
