Features:

●  Our 7. 3m earth station antennas is Cassegrain type with optimized design and advanced manufacture technology .The metal (stainless steel)of them are dealt with hot-dip zinc technology which can prevent zinc from volatilization.

●   Our 7. 3m earth station antennas  meet requirements of CCIR580 and INTERSAT and the minimum life expectancy of them can be ensured 15years.

●   We can supply manual or motorized transmission mode with two-axis or three-axis 7.3m earth station antennas .The customer can choose 2 ports , 3 ports or 4 ports 7.3m earth station antennas.

●    The deicing and snowmelt equipments of  7.3m earth station antennacan be installed on the main reflector with automatic control and the rain , snow blowing devices can be  put on the feed  as well.  We can also supply the lightning protection and grounding devices , Light control aviation warning devices.


Advantages:

●  The  7.3m earth station antennas are convenient for installation , the reflector can be interchanged freely and having high precision re-installation .

●  Our company take effective measures to lower the cross polarization level of our  earth station antennas,the result of test which is cross polarization isolation is high level(Beam center is over 35dB)


Applications:  

●   Telecommunication departments

●   Gate station

●  Seismological Bureau , roads and traffic authority .governments and so on

●  Remote sensing

●  State Weather Bureau
