Broadband Specification Guide Signal From DBS (DishNetwork ) Satellite Functionality This system will allow you to receive any channel that is available via the small dish satellite and distribute it through the facility. This signal can now be handed off to a traditional coaxial distribution network or a hybrid fiber/coaxial distribution network within the facility. In the early 1990’s the advent of the high power, direct broadcast satellite marked a turning point for reception of satellite signals. Prior to DBS, very large satellite antennas (10 + feet), or dishes, were required to receive and amplify programming. The average commercial grade DBS is no more that 3 feet across, and can be mounted virtually anywhere. The reception and processing of DBS satellite signals in theory is no different than the off air models presented earlier, there are only differences in the electronics employed to do the job. In Depth Description The start of the system is the dish itself. There are many different types of DBS satellite dishes and mounts on the market, each intended for a different purpose. It is critical to the system operation that the satellite dish and LNBf are matched for proper operation. The correct units are based upon the desired programming to be received. The site must have a dish mounted on the outside of the building to receive these signals. If there is not adequate reception to hand off to the satellite receiver, an in-line amplifier may need to be employed. Since the necessity of an in-line amplifier can not be determined until a site survey is performed, it is advisable to specify the in-line amplifier, “as required by site survey”. The satellite receiver is the piece of electronics that accepts the signal from the satellite dish, and provides a baseband audio and video that can be presented to a modulator. It is the job of the modulator to take the audio and video and make them in to a cable TV channel. This channel can then be combined with other locally generated channels or a cable TV feed. This combining should be done with professional quality equipment and at the correct level to prevent the channels from interfering with each other. If you pick one product from each category on the next page, you will have all of the components to ensure a working design. Once all of the products are identified, the specifications can be looked up in the specification library at the end of this publication. 44
