Mast for satellite antenna, esp. on vehicle

摘要

The mast includes a tubular mast (1) and a coaxial element (2) integral with the mast. Inside the mast is a worm gear (3) mounted on a shaft (4), oriented downwards through a central hole to a hand wheel (5) for varying the inclination of the antenna. This can be blocked by a pin (7) which is pushed through an aperture in a bar (8) coupled to a second worm gear (10). This worm gear meshes with a toothed (11) wheel (12) fixed in a half shell (14), allowing the antenna holder to be rotated.
