Best 3M VSAT C/ku Band Antenna Manufacturer & suppliers

1. Overview of 3M VSAT C/ku Band Antenna

Antesky ATSK-300CST or ATSK-300KST 3.0-Meter is a aluminum parabolic antenna, reliable antenna system that will operate at C-band, Ku-band frequencies with high efficiency and at the same time successfully withstand the effects of the environment. This antenna adopts reflector which consist of precisely formed aluminum plate with matched back structures and hub assemblies for the easy installation. The 3.0m reflector is supported by a galvanized steel kingpost that provides the required stiffness for pointing and tracking accuracy. 3.0m dish antenna can be installed on the ground or rooftop. Antesky 3.0m antenna systems are available for a wide range of applications including wireless telecommunication service providers, Internet service provider, system operators and broadcasters throughout the world.

2. Key Features and production technology of 3M VSAT C/ku Band Antenna

Features:

Parabolic receive only antenna with front feed;
Single kingpost type pedestal;
Manual adjustment;
High gain, low sidelobe, high cross-isolation;
C/Ku band, linear/circular polarization.

Process:

The antenna reflectoris stretched and molded by aluminum sheet to ensure the high precision of the antenna reflector.
Three test methods are used to ensure high-quality delivery of antennas: reflectoraccuracy test, assembly test, electrical performance test.
Pre-treatment: antenna panel cleaning and degreasing; steel structure parts are zinc-blasted, sand-blasted or hot-dip galvanized.
Surface treatment: apply zinc yellow primer first, then white topcoat, double protection, improve antenna anti-corrosion ability.
