Inside a VuQube

Have you ever wondered what's inside the NEW mini motorized satellite antenna to go? Well now you don't need to!Well it's a mini cassegrain satellite dish, this little beauty works just as good if not better than a regular 18" dish! If you look at Wikipedia under cassegrain you can read about the benefits of this design of satellite dish!AMAZING! http://en.wikipedia.org/wiki/C... Cassegrain reflector is a combination of two coaxial reflectors used in Cassegrain telescopes and radio antennas.First developed in 1672 by Laurent Cassegrain, this reflector is a combination of a primary concave mirror and a secondary convex mirror, both aligned symmetrically about the optical axis. The primary mirror usually contains a hole in the centre thus permitting the light to reach an eyepiece, a camera, or a light detector. The primary mirror is parabolic while the secondary mirror is hyperbolic.Of the three basic types of telescopes: refractors, reflectors and catadioptrics, the Cassegrain reflector falls under the categories of reflecting and Catadioptric designs.Cassegrain designs are also utilized in satellite telecommunications earth station antennas, ranging in size from 6.3 metres to 14 metres. The centrally located sub-reflector serves to focus radio frequency signals in a similar fashion to optical telescopes."
