|The AvL Ka-Band Mobile VSAT IP Broadband Antenna System (1.2m) is certified to operate on the ViaSat Exede service.|
AvL’s Ka-Band Broadband Antenna Family offers high reliability, cost-effective solutions for mobile broadband Internet access with new HTS satellites.
These antennas feature the AvL Zero Backlash Cable Drive and an Auto-Acquisition Controller.
AvL’s Ka Broadband antennas are available in the following sizes:
- 85cm (model 880KVH)
- 1.0m (model 1080KVH)
- 1.2m (model 1280KVH)
The antennas offer cost-effective solutions for mobile broadband Internet access, Satellite News Gathering, Disaster Relief, Oil & Gas Data Backhaul,
and Defense & Homeland Security. Antennas in the Models 880KVH / 1080KVH / 1280KVH Ka Broadband Antenna Family operate with:
- Avanti / HYLAS
- Eutelsat / Tooway
- ViaSat / Exede
AvL Auto Acquisition Controller
AvL antenna systems combine the patented AvL Cable Drive positioning system with totally automatic satellite acquisition to provide ease of operation
(without a satellite technician) and ultimate reliability under even the most demanding environmental conditions. Our auto-acquisition controllers contain
embedded software (no software to install!) to automatically find the satellite in minutes providing rapid deployment and operation on any satellite worldwide.
Compatible with every satellite modem without modem interface required, the controllers have integrated GPS to determine exact site location, compass,
base level sensors, and a receiver that allows satellite acquisition and optimum peaking and cross pol nulling without any connection to the RF system
resulting in automatic optimization of azimuth and elevation and polarization alignment.
Safety features include shut off of receive link if movement is detected and a stow command if the vehicle moves or tilt sensors are activated.
AvL Cable Drive
The AvL Cable Drive rotary drive system suffers no backlash and is a simple maintainence free dry mechanism able to operate in a very wide range of difficult and
hazardous conditions without degradation.
The AvL Cable Drive rotary drive technology is an elegant, simple, system that utilizes the averaging effect of many cables wrapped around a drive capstan and
an output shaft.
The most important of specifications for a satellite antenna, particularly an auto-acquisition antenna, is the pointing accuracy and the stability and stiffness
of the positioner under the most extreme environmental conditions. The positioning accuracy is determined by how precisely the positioner can move to a defined
point as well as how stable and stiff the positioner is in maintaining that position. The speed of movement is based on how quickly the positioner can move to
a defined position.
AvL’s patent-pending AvL Cable Drive technology provides the ultimate in precision and stiffness compared to geared drive systems and, unlike most other systems,
is free of backlash. It is a maintenance-free dry mechanism able to operate in a very wide range of difficult and hazardous conditions without degradation.
Originally invented as an inexpensive way to rotate very large antennas accurately and smoothly, the AvL Cable Drive is an elegantly simple system that utilizes
the averaging effect of many cables wrapped around a drive capstan and output shaft.
