Model 6.3M Compact Cassegrain Antenna
The VertexRSI 6.3-meter Compact Cassegrain Antenna delivers exceptional
performance for transmit/receive and receive only applications for
C through Ka-band frequencies.
This antenna offers a deep dish
reflector that incorporates precision-formed panels, contoured
radials and a machined hub assembly. It features an innovative
Compact Cassegrain feed and subreflector design which results
in high gain, low noise temperature, high antenna efficiency and
excellent rejection of noise and microwave interference. The
reflector is supported by a galvanized kingpost pedestal that
provides the required stiffness for pointing and tracking accuracy.
The pedestals are designed for full orbital arc coverage and
are readily adaptable to ground or rooftop installations. The
electrical performance is compliant with FCC 25.209 and ITURS-
580 sidelobe specifications. Type Approved configurations
are available for Intelsat (F2, E2), Asiasat, Hispasat or Singapore
Telecom. All configurations meet SATCOM Technologies’ own
type-approved quality assurance and performance guarantee.
