Reliability of the Satellite Trailer

The Lewis and Clark Expedition has used it:

Every day for 6 months

At over 100 different rural locations

Over 3500 miles traveled, including rough roads

With NO FAILURES

PS - They now set it up in 7 minutes, using 2 people.

Type of power Running Time

Also provides power to user-supplied equipment.


Aiming System

Satellites are 2 degrees apart in the sky; aiming accuracy must be better than 1/2 degree.

GPS Receiver provides accurate local position to PC. (or just use Zip code)

PC calculates azimuth, elevation and polarization settings. (or just use provided aiming maps)

Dish is aimed with precision compass and inclinometer, using simple adjustments. Azimuth - motor drive Elevation - hand operated turnbuckle

NO hand tools required.


Weatherproof Equipment Rack Cabinet


Mounted on shock absorbers.

Automatic thermostatically controlled heater.

Automatic thermostatically controlled ventilation fan.

No actual air cooling. Use provided parasol if needed.

Latest State-of-the Art Wireless Antenna Technology

To achieve long range, wireless antennas MUST be directional.

That requires careful aiming of the antenna at distant user.

All distant users must be in the same direction.

New phased array antenna:

Aiming is done automatically and electrically. No actual physical aiming of the antenna. Covers a full sector all at once. Longer range than ANY other antenna.
