The device you are saying cannot be used because the cable connectors are different from the Coaxial cable used for DTH signals.
For receiving 2 satellite either we can run 2 cables from dish to STB, but it has disadvantage of increased cable cost and possible damage to STB tuner if STB not powered OFF.
DiSEqC (DiSEqC - Wikipedia, the free encyclopedia) is good solution, but as DTH concept is a new in most parts of country so don't know availability & cost of it. And therefore I even see rare chance of availability of motorised dish (Satellite dish - Wikipedia, the free encyclopedia).
But more important of all, does
Tata Sky STB supports DiSEqC or Motorised dish. If not,TRAI/BIS standards must make it mandatory for all providers to provide STB with above support
Oh..kay, i was thinking of this only.
Nways to make things simpler isn't it possible to get a 2nd dd direct stb and get it connected to the cable point using the cable connector and
tata sky using the red whit yellow wires to the av unit of the
tv. So we'll get tata sky in the av channel and in normal tv on a particular channel we'll get dd direct channels.
I mean this a soltn think but may be a bit costly... as far as I know dd direct can be accessed thru cheap stbs openly available... any idea how much they cost.
Please dont mind i'm really a novice in all these and not thorough with exact terminologies.
