Features:

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

●  After studing factors of XPD, we take effective measures to lower the antenna cross polarization level.

● 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 a satellite antenna manufacturer, 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 advantages 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 ACU made by manufacturer appointed by users.


The 11.3m earth station antenna has the following advantages:

● Cassegrain type with the optimized design and advanced manufacturing technology, high gain, low side lobe, small VSWR and so on. Our antenna meets the requirements of CCIR580 and INTERSAT.

● All the metal of the antenna is 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 has compatibility of C, Ku, X and L bands, when the end user wants to use new band, they do not need to purchase a new antenna. By changing the band system, they can realize new functions required.

● 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 is widely used for news gathering.

● It can be used for energy survey.

● It can be used by Ministry of Water Resources.
