Now now.....how the thing works is this way.....get a decoder, buy a "multiplexer device". Connect the decoder to this multiplexer device, from where you have multiple connections which you can redistribute to probably 6 to 7 people at most. So these guys who you have distributed the signal to, will just have to connect this cable to their sets, do a channel search and there will be the dstv channels they are so much yearning for. If you want to distribute the channels to many many people, you have to get a decoder for each channel, connect the decoders to the multiplexer device and redistribute.
As for where the devices are available from, tunaweza onana kando, but be forewarned, the fines for this kind of dstv-signal-distribution range from 800k to about a milli, so evaluate whether its worth the risk venturing into the business......my 0.4 otonglo.
