Features:

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

●  Lucubrating factors of XPD , we take effective measures to lower the antenna cross polarization level .  the result of test which is cross polarization isolation is high level(Beam center is over 35dB)

● Since the installation precision of the sub reflector has a strong effect on the electronic performance of ground antenna , we have developed sub reflector and will provide them to the users, the installation of the sub reflector is simple to master ,and thus to avoid decreasing the antenna performance .

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

As satellite antenna manufacture ,Our company provides not only various kinds of satellite communication products but also a full set of service including the engineering design , installation , adjustments, maintenance and training with advantage ,of its solid technology background ,abundant engineering experience and advanced devices and equipments . We will design produce and supply appropriate  transition components in accordance with the ODU made by manufacturer appointed by users .


The 11.3m earth station antenna have the following advantages :

● It has Cassegrain type use the optimized design and advanced manufacture technology .they have high gain ,low side lobe ,small VSWR and so on .our antenna meet requirements of CCIR580 and INTERSAT .

● All of metal of antenna are made by hot-dip zinc technology to 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 .

● The 11.3m earth station antenna has motorized transmission mode with two-axis and three axis.

● The 11m earth station antenna have compatibility of C, Ku ,X and L band ,when the end user want to use new band , they do not need to purchase a new antenna , as long as they change the band system , they can realize to change the new band and meet requirements .

● According to the requirements of end user , 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 11.3m earth station antenna .


Applications:  

● It widely used for news gathering .

● It can be used for energy survey .

● This kind of 11.3m antenna can be used for Ministry of Water Resources.
