AvL Technologies: Focusing on Technical Excellence – Designs for Ultimate Performance

By | September 1, 2010 | Satellite TODAY News Feed

AvL Technologies designs and manufactures motorized, mobile satellite antennas that exclusively combine the original patented Roto-Lok® cable drive, world-class AvL carbon-fiber reflectors, and the unique one-button auto-acquisition controller to automatically locate and lock-on the satellite signal within minutes. With decades of satellite antenna experience (on satellites, payloads, and on earth stations) behind our engineering, AvL is the premier antenna-only manufacturer in the satellite industry, leading the way in producing mobile earth stations that are functional, reliable, and technically excellent. 

Pointing Accuracy, Stability, And Speed Of Movement

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. AvL created the original cable drive technology to provide the ultimate in precision and stiffness compared to geared drive systems. Unlike most other systems, the cable drive 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

High Performance Carbon Fiber Antennas

The AvL reflectors range in aperture size from .75 M to 2.4M. Solid and segmented carbon-fiber antennas are ideal for vehicle-mounted and flyaway configurations for SNG and VSAT applications. The robust 2.0M reflectors, both segmented and solid, perform exceptionally with C, X, Ku, DBS, and Ka feeds. In fact, all reflectors are of accuracy to allow use at Ka band. Each is laser tracked at AvL’s test area prior to shipment to re-verify surface rms and produce “text book” patterns with margin to 29-25 log ΘT curve required by FCC, IntelSat and other international carriers, including Eutelsat.
In 2010, the SNG product range was completely updated introducing unique capabilities and additional customer benefits including significantly lighter weights, lower stow heights, greater stiffness and dramatically better styling.  For the increasingly popular larger vehicle mount antennas (2.0M and 2.4M) AvL introduced manually and electrically deployable “wings” that allow these antennas to be mounted on standard panel vans such as the Mercedes Sprinter and similar vehicles popular in the broadcast service market.
