Overview

AvL’s 1.8m vehicle-mount / drive away SNG antenna systems offer strong performance in a small, lightweight and low-profile package. The 1.8m antenna systems offer standard Ku-band, with L- and X-band optional. The antennas feature integrated GPS and level sensors for automatic vehicle tilt compensation.

AvL’s SNG antennas are designed to meet and exceed the highest performance requirements around the world to guarantee both satellite authority compliance and peak in performance, reliability and availability. Typically these antennas are used in signal contribution for high data rate and bandwidth as well as high power broadcast or similar applications.

AvL Vehicle-Mount / DriveAway Premium SNG/MIL Antenna Systems feature:

High-precision azimuth bearing

Non-load-bearing Carbon Fiber reflectors with surface treatment for Ka-Band

Integrated backing structure for minimized stow height

Wide booms to allow larger HPA envelope

Jog control or fully automatic auto-acquisition controllers

Feed options for Ku-, Ka- and X-band; optional C-band for international

RF electronic mounting either on feed boom, back of reflector, base, or inside vehicle

25ft (8m) RG59 coax and controller interconnect cables

Aerodynamic cowlings are available for some apertures
