Abstract
A mounting assembly including a casing having an outer surface attached to a TVRO antenna and having an inner surface and at least one first guide slot positioned on the inner surface of the casing. An inner tube is located inside the casing and has portions which extend out of the casing for attaching to the mounting pole. At least one second guide slot is formed through the inner tube. One of the first or second guide slots is non-linear. The casing is rotated by a spider-like mechanism having drive arm having a first end nested in the first guide slot, a body passing through the second guide slot. A leadscrew passes through the spider like mechanism and a motor coupled to one end of the leadscrew turns the leadscrew causing the spider like mechanism to move vertically along the leadscrew, which in turn causes the casing to rotate with respect to the inner tube.
