1.8M Flyaway antenna Introduction

Posted by terry on almost 6 years ago.
1.8M Flyaway antenna is satellite communication antenna with the advantage of miniaturization and portability, which possesses the characteristics of small volume, light weight, quick assembly, and high precision of reassembly. Generally the flyaway antenna is packed in a backpack or a small box.
 

According to the feed position, flyaway antenna can be divided into two categories, which are prime focus and offset antenna. In the market mostly it is offset antenna, which is consisted by reflector, feed system, azimuth adjustable equipment, and elevation adjustable equipment and tripod pedestal mount. According to the material, it can be divided into two categories, which are aluminum and fiber antenna.
Take Antesky 1.8m flyaway antenna as an example.
