Product Details

Introduction:

As one of the best satellite antenna manufacturers in China, we provide the following 3.0m earth station antennas:

Manual or motorized 3.0m C-band earth station antenna

Manual or motorized 3.0m Ku-band earth station antenna

 Antenna control system

● Tracking receiver


As a satellite antenna manufacturer, our company provides not only various kinds of satellite communication products but also matched service, such as the engineering design, installation , adjustments, maintenance and training with advantages of its solid technology background, abundant engineering experience and advanced devices and equipments. 

The antenna is convenient for installation, and the reflector can be interchanged freely and it has high precision re-installation performance.

We take effective measures to lower the antenna cross polarization level.

We develop and provide sub reflector to users to avoid the strong effect of the installation precision of the sub reflector on the electronic performance of ground antenna, and the installation of the sub reflector is simple to master.

Fine–adjusting facilities and the Az-EL locking device are designed for all types of our earth station antennas.

Features:

 It has high gain, low side lobe, small VSWR and so on. Our antenna meets requirements of CCIR580 and INTERSAT.

● All the metal of the antenna is made by hot-dip zinc which can prevent zinc from volatilization. All hard wares adopt stainless steel to ensure the antenna’s 15 years minimum life expectancy even if it is in bad environments.

● Our antenna has manual or motorized transmission mode.

● Our ground antenna has linear polarization and circular polarization feed, and you can choose 2 ports, 3 ports or 4 ports. The linear polarization can be changed to circular polarization automatically.

● It has compatibility of C and Ku band, when customer wants to use new band, you can only change the band system instead of purchasing new antennas to meet new requirements.

● We can install the deicing and snowmelt equipments on the main reflector with automatic control and put the rain and snow blowing device on feed. We also can equip the lightning protection and grounding device, light control aviation warning device for the 3.0m earth station antenna.


Applications :  

● Our 3.0m earth station antenna can be used for roads and traffic authority of governments .

 It is widely used by environmental protection authorites. 

 It  is widely used in radio and television .
