System Overview

The SR1500 antenna system provides live satellite TV to a vehicle, while in motion. It
is suitable for installation on any vehicle. It includes a receive panel and electronic
circuits, and is designed, built, and ruggedized for outdoor operation.

Figure 3: SR1500 antenna

The SR1500 antenna is available in two versions:



Uni Pol

(one cable connection) antenna model supports a single TV screen –

one user on one channel at a time.



Dual Pol

(three cable connections) antenna can service multiple TV screens,

with each passenger able to access a different channel. The Dual Pol model is

useful on buses.

Accordingly to the version selected, either one or three cables are routed from the
antenna to the indoor compartment.
