9 Cable Distribution System

What is a 9 cable distribution system? Consequently this 9 cable system is used, to distribute satellite signal to multiple points. Most commonly this system is used in Multi Unit Dwellings (MUD). Nine cable distribution systems therefore uses, a 9 cable multiswitch reticulation system. Two different satellites can be provided for compared to the 5 cable system. This is possible due to DiSEqC technology.

What is a multiswitch?

Multiswitch is used to connect decoders, to the 9 cable system. Therefore it enables the decoders to switch between available user bands. Decoders will only be able to switch between user bands, supported by the 9 cable system. 

9 Cable Multiswitch

First of all a nine cable distribution system, makes use of 9 cables between multiswitches. Therefore this system is referred to as a 9 cable reticulation systems. In addition a 9 cable multiswitch enables decoders to switch between eight user bands. Furthermore this kind of multiswitch also allows for the reticulation of terrestrial antenna signal.

What is DiSEqC (Digital Satellite Equipment Control)

  • DiSEqC commands are carried on the supply voltage in the co-ax cable to the switch just like the polarization and frequency selection commands going to the LNBs
  • Eutelsat apparently developed the system to allow satellite users in Continental Europe to switch between the more popular SES Astra satellites at 19.2° east and Eutelsat’s own Hot Bird system at 13° east

a 9 Cable system uses DiSEqC to switch between different satellites. Therefore you are able to access more service providers.

9 Cable Reticulation

What is nine cable distribution? Since in most applications, many users requires a satellite signal from one or two dishes. Therefore to make this possible, a satellite distribution system is required. Rather than having many separate dishes installed. One or two dish feeds to all the users. We therefore use 9 cables in a, 9 cable distribution system. These nine cables is supply 9 different signals. 

a Amplifier, amplifies antenna signal, as well as the eight user bands from a couple of satellite dishes. nine outputs supply signal from the amplifier. Furthermore these nine cables, gets reticulated to a series of multiswithes. Consequently the 9 cable multiswitches is in turn, supplying outlets at each user with signal. Finally a outlet in turn separates the signal into, antenna and a single satellite signal.

Explora decoders and Xtra View installations use more than one tuner. Therefore more than one cable, from the 9 cable multiswitch is required. Mulichoice recommend 4 cables to a unit. Some existing systems do not allow for more than one cable to a unit. If this is the case have a look at our SCR solution.

Multichoice recommend a distribution system that allows for four user band. a Nine cable system is high band complaint. Therefore 9 cable systems are ready for DStv’s service expansion. In addition a 9 cable system will also allow for other service providers.
