Specifies a multiple outlet wired distribution system for the distribution of HF, VHF television signals or VHF FM-radio signals. The system described is a common antenna system for obtaining broadcast signals but the system is capable of distributing radio or video signals from any source over a network of cables, or a suitable alternative, subject to certain performance requirements. Performance is measured in terms of the electrical parameters at the system outlets. The requirements are technically identical with those of IEC 728.
