A-Line Series 6m ANTENNA
Overview
Advantech Wireless A-Line Series antennas are designed and manufactured in
batches with 6-meter Dual-shaped Compact Cassegrain all aluminum reflector
antenna for VSAT applications in both C band (Model C3956T) and Ku band
(Model K6T).
The A-Line Series C3956T and K6T models adopt a precision-formed reflector
mounted on an Az over El pedestal providing necessary stiffness and pointing
accuracy required in C and Ku band operation. It is provided with a feed with
corrugated horn and OMT and is of optimized R.F. specifications, operates in
circular or linear polarization selectable manually and meets any requirements
of customers for particular applications.
The A-Line Series C3956T and K6T antennas meet the regulations of CCIR
580-4 and have been approved by ASIASAT, INTELSAT, CHINASAT, etc.
