This Standard sets out specifications that relate to the design, installation, electrical safety aspects and working performance of a range of Radio Frequency (RF) distribution systems along with passive and active components that will enable the high quality distribution of analog and/or digital television and sound signals in single homes and multiple unit dwellings. The end result of compliant systems and components is to make available RF based broadcast or in-house signals carried by coaxial cable or by a combination of coaxial cable and fibre optic cable, to one or several outlets in a user's dwelling(s) and then onto a user’s receiver where a tuner may reliably select and decode the desired signal with minimum distortion or interference. The scope is illustrated in Figure 1.1. This Standard is applicable to systems capable of accommodating the distribution of RF signals depending on service requirements that may include interactive return path, over a frequency range that may cover from 5 MHz to 2150 MHz.This Standard covers distribution systems that typically carry, as a minimum, the local Analog TV and Digital TV Free-To-Air (FTA) terrestrially broadcast services, through to extensive systems that combine terrestrial and satellite IF (single or multiple) distribution and also may separately distribute Cable services.This Standard provides specifications for a range of passive and active devices including coaxial cable. The specification compliance of individual components performance and the interaction between them is seen as an essential primary requirement to provide a design that has predictable level and quality outcomes leading to robust overall performance that is presented to the user’s connection point (system outlet or 'wallplate'). This Standard provides level and quality parameters applicable to the final system for both design guidance and system commissioning.This Standard provides examples of system topology and although applying limitations the Standard is not intended to restrict other potentially compliant system topologies.
