适用范围：This Code of Practice covers recommendations for the erection, cabling, performance and safety requirements of the Master Antennae Television Systems (MATV) for the reception of VHF and UHF Sound and Television Broadcast Transmission operating between 5 MHz and 824 MHz.The recommendations have included, as far as possible, certain aspects of Cable TV (CATV) distribution. The MATV system so wired will result in minimum changes on introduction of new services such as CATV or multipoint microwave distribution services.When it is converted for CATV operation, there will be no major system wiring change. However, the installation of additional passive and active devices such as filters, decoders, reverse signal path amplifiers, interdiction equipment etc. may be required. Minor adjustments of the signal levels at various distribution points may also be required. There will be no change to the subscribers' feeders.NOTE. Compliance with the recommendations given in this Code does not counter immunity from relevant legal requirements, such as regulations issued by the Telecommunication Authority of Singapore, Ministry of Information and the Arts, and the Public Utilities Board.
