VM90/120
Vsat Vehicle Mount
Drive-Away Antenna
• 90cm to 1.2M Reflector options
• Dual optic SMC antenna
• Exceptional Value
• Compact and Robust
• Simple Auto-Acquire satellite control
Compact
The VM antenna is a high quality roof mount
system which encompasses the drive control,
positioning hardware and amplifier into the
antenna enclosure, making the system a
robust standalone sub-assembly ready to
install onto almost any vehicle.
Auto-Acquire
The Satellite Acquisition Controller uses
industry standard position transducers and a
sophisticated pattern recognition algorithm to
confirm and refine its heading information
using visible satellites. The controller is
mounted on the antenna structure with a
separate power supply and control panel in a
rack mount unit for mounting within the
equipment area.
Easy of use
Options :Vehicle mounting brackets
De-Ice Kit
3 axis Jog-controller
Auto-Pointing controller
Inclined orbit tracking controller
The system is simple to install, set up and use.
Following relocation of the antenna, the
system will reliably and accurately locate and
lock on to the designated traffic satellite
rapidly within minutes.
