PRODUCT DETAILS

Introduction:

We are the one of the best satellite antenna manufacture in china.

Our major business of antenna is following:

 manual or motorized 3 M C-band earth station antennas

● manual or motorized 3 M KU-band earth station antennas

 Antenna control system

● Tracking receiver


As satellite antenna manufacture, 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 advantage ,of its solid technology background ,abundant engineering experience and advanced devices and equipments . 

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

We take effective measures to lower the antenna cross polarization level to research factors of XDU.  The result of test which is cross polarization isolation is high level.

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

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

Features:

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

● All metal antennas are 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 which you can choose 2 ports, 3 ports or 4 ports. The linear polarization can be changed to circular polarization automatically.

● It have compatibility of C and Ku band , when customer wants to use new band , you can only change the band system instead of purchase new antennas, and meet 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 3.0m earth station antenna.


Applications :  

● 3m earth station antenna can be use for  roads and traffic authority of governments .

 It is widely used for environmental protection authorites. 

 It  is widely used in radio and television .
