1.Signal Source: Satellite receiving dishes, terrestrial TV antennas and local program devices such as media players and cameras, which output AV audio & video signals.
2.Headend Equipment: Analog modulators, RF mixers and trunk amplifiers to process all TV signals in the equipment room. Each TV channel requires one analog modulator, and the mixer combines all channel signals into one single trunk RF signal.
3.Coaxial Transmission Network: Coaxial cables serve as the transmission medium. Equipped with trunk amplifiers, splitters and distributors to deliver signals to each room. No optical fiber equipment is needed for pure analog systems.
4.User Terminals: Analog TVs with RF interfaces, no set-top boxes required.
Calculate coverage scale and total number of TV channels;
Wire all source devices to modulators, then connect modulators to mixers and amplifiers in the equipment room;
Lay coaxial trunk cables and install splitters & distributors for each household or guest room;
Adjust signal level with testing instruments to eliminate picture noise and interference.
