Introduction
About the Gilat SR1500
The Gilat SpeedRay™ 1500 (SR1500) is the innovative antenna system that provides
live satellite TV to a vehicle, while in motion. This manual provides basic instructions
on how to install the antenna and controller in most vehicles and operate it safely.
Signal Reception
The SR1500 antenna can be used to receive satellite television via the Direct
Broadcast Satellite (DBS) satellites, located 35,000 km in space. This system requires
a clear view to the skies above the equator to maximize the signal reception. Other
factors, such as satellite coverage area, elevation angle, and weather also contribute
to the signal quality.

Satellite Coverage
You must be located within the satellite’s coverage area for proper reception. As you
begin to travel outside of this coverage area, the signal becomes weaker.
Azimuth and Elevation
The DBS satellites are located in the skies above the equator. The SR1500 is a
sophisticated mobile antenna with a satellite recognition and tracking system. The
antenna automatically determines and maintains the proper azimuth and elevation
angle without user intervention. This enables the system to receive satellite TV while
stationary or in motion.
