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.

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.
