DSTV Signal Changes
Multichoice is in the process of upgrading their channel capacity and quality. This change that is scheduled to occur somewhere between 2016 and 2017 will require that all subscribers receive the four different polarities or quadrants down to their decoders, which will need to arrive in 4 separate coax cables. The preparation for these changes has already been done in the form of the new decoder and accessory devices, specifically the new DSTV explorer and its requirements to use the 5-in-1 or 5-in-2 switch which converts the 4 cables onto 1 cable which uses a different signalling type called Unicable or SATCR.
Please note that currently only two are required, but not heeding the recommendations by Multi-Choice may require additional re-installation within the next year or two.
The four quadrants or polarities are:
- Vertical High ( Y axis + )
- Vertical Low ( Y axis – )
- Horizontal High ( X axis + )
- Horizontal Low ( X axis – )
