Table of Contents Figure 12. AFC CH-14 conical horn. Summary Satellites and programmers are on the move. Syndicates formed by major program providers and satellite manufacturers are forcing a monumental review of headend antenna needs. To retain and receive the various programming services, cable operators are faced with a series of antenna challenges and choices which determine the picture quality of their delivered product.
Parabolic antennas continue to dominate the single satellite application.
When antenna mount and foundations are designed to accommodate environmental wind loads, pointing accuracy and system gain are maintained. Performance data on MSF system antennas are described-giving gain reduction as a function of scan angle. Lastly, the spatial filter representation of an antenna is investigated. The conical horn is shown to give another 40 dB interference rejection headroom over the parabolic antenna. AFC manufactures, markets and sells worldwide satellite dish antennas, conical horn antennas, radomes , antenna feeds, microwave and waveguide components, ultra low loss waveguide transmission line Tallguide , and custom shelters.
