VSAT 4.5M ANTENNA

   NWIEE designs and manufactures in batches 4.5-meter aluminum reflector antenna for VSAT applications in C band (Model VS4.5C) and Ku band (Model VS4.5Ku).

4.5M antenna adopts Dual Shaped Compact Cassegrain precision-formed reflector mounted on a Az.over El. pedestal providing necessary stiffness and pointing accuracy required in C and Ku band operation. It is provided with a Rx/Tx (2 ports) feed with corrugated horn and OMT and is of optimized R.F. specification, operates in circular or linear polarization selectable manually and meets any requirements of customers for particular applications.
 4.5M antenna meet the regulations of CCIR 580-4 and have been type approved by ASIASAT and INTELSAT. NWIEE 4.5M antenna can enter ASIASAT-2 and INTELSAT Network without the need of certification test after installation on sites.
