摘要 |
<p>A DBS antenna comprises a support arn (10) which at its front end supports a converter/feed unit (12) and at its rear end is secured to a mounting bracket. The antenna dish (14) is mounted on the support arm (10), so that the dish (14) is supported by the arm (10) without mechanical loading from the converter/feed unit (12). The converter feed unit (12) may have a tapering cover portion (74) of sufficient electrical thickness to produce focussing of the signal into the waveguide feed.</p> |
