Upgrade today from your Rantec antenna to the latest version of Viasat's VR series Antenna System
Ku-band VR-12C Advanced Antenna
- The Rantec antenna is belt driven and unreliable, costly and obsolete as of May 2018
- The Rantec antenna has no repair capabilities and used parts are difficult to find and come with no warranty.
- The new VR-12C antenna uses precision bearings which make it highly reliable.
- The VR-12C antenna has 3x’s the download speed as compared to the Rantec antenna.
- Increased operational area within the satellite beam resulting in improved connectivity.
VR-12C Product Improvements
User Benefits
- Form/Fit/Function Equivalent to VR-12T (except for power wiring changes)
- Compatible with existing ArcLight modems
- Replaces existing 10-watt SSPA with new 20-watt SSPA
- Extended receive band: 10.95-12.75 GHz (Standard Product: 11.55-12.75 GHz)
- Band switching controlled by modem via ACU
- Incorporates redesigned azimuth bearing and drive motor for increased reliability
- Slip ring reliability improvement over VR-12T
- Qualified to lasted RTCA DO-160G
User Benefits
- Potential to double transmit and return link data rate
- Means more data can be pushed off the plane
- Statement is service plan dependent, see next page
- Increases operational area within satellite beam
- Extended Rx band opens up use of other Ku-band satellites and bandwidth
