Multiswitch SMATV system in a 5-staircase building

The requirements for the building installations included SMATV system providing each outlet with DVB-T and SAT signals (from a single Hot Bird position).

The building has five staircases with a 40 m spacing. There is an underground garage in the basement below the ground level (first flloor). The basement should be used for the distribution of the signals to all the staircases (the investor did not want separate systems in individual staicases) via a bus composed of five Triset-11 PE E1025 cables.

Due to a large number of the outlets in the building (ca. 300), the optimum choice was multiswitch system based on a bus architecture and MSV-5xx multiswitches.

 

In this implementation, three stories in each staircase have been equipped with MSV-516 R70716 multiswitch and satellite splitter or tap from Terra SS-5xx series with the loss resulting from the energetic balance. The exception is the last, fourth floor, equipped in each staircase only with the MSV-516 R70716 multiswitch. The total number of outlets in each staircase is about 60.

The system is powered from SA 501 R70501 amplifiers located in each staircase, via H lines.
