Model 1.2m SMK-LT Ku-Band Antenna
Mobile Antennas
Description
The VertexRSI lightweight 1.2-meter mobile antenna is
designed for worldwide transmit and receive operation in
Ku-band. This transportable antenna consists of a single-piece
carbon fiber composite reflector mounted on a cable drive
elevation-over-azimuth positioner. This results in a low-weight
antenna with superior stiffness and high performance under
wind loading conditions.
The state-of-the-art design provides exceptionally low
sidelobe and cross-polarization performance, well within
INTELSAT and EUTELSAT requirements.
The complete antenna system can be interfaced with most
lightweight vehicle structures for the purpose of mobile SNG
applications.
