Dawson GC-Zero answers the needs of communications professionals with a low profile antenna system. The very low profile ( 240 mm ) antenna ensures that vehicle heights are not compromised by the fitting of the communications system. 'Fit and Forget ' reliability with long, reliable, proven quality in the harshest of conditions

Applications

Emergency Services Communications, Military Communications, Cell Phone Extension Fire, Police and Rescue services.

Functionality

With fully automatic pointing the system is simple to set up and use. A simple user interface requires no special training but gives the operator full control if required. With built in inclinometer, GPS receiver and DVB receiver built in and fully controlled the operator can concentrate on other important tasks.

Design

The system has been designed taking into account Dawson's extensive experience to make the solution light, rugged and fast to deploy but wile still retaining the Dawson reputation for quality and value with the system costing a fraction of competitive equipment.

Ease of use

The system operates from Dawson custom software that is pre programmed to search for the required satellite using the built in DVB receiver. The operational interface is a simple three button. One for deploy, One for stow and an emergency stop. The display also provides a progress meter and a Eb/No meter so that pointing progress can be monitored from the main screen. The software also provides manual control of the antenna if required as well as detailed diagnostics to assist with the unlikely event of fault finding. There are even manual push buttons on the controller to give complete redundancy of control.

Compatibility

With the system so light and compact it can be fitted to virtually any base vehicle, especially with the low stow height and light weight, this gives flexibility to coachbuilders pushed for height restrictions.
