Hey, have not you seen the big dishes kept in the transmission offices??? I just saw this Chennai SD Office.. with BIG Dishes and satellite up linkers.
It is not the size of dish which matters.
Its whether you use Ku Band signals or C band signals, and on the frequency of the waves.
Tata Sky uses KU band signals, which are effected more by rain than C band signals.
Remember during IPL, during one of the matches when the IPL had just begun this yr, it was raining in the Stadium. The picture was cutting and it looked just like what happens when it rains in our city and our signals are disrupted.
I thought it was some problem with TS only but then you heard the commentators, they said, we're sorry for the signal disruption, due to cloud cover over the stadium we are having difficulties in broadcasting signals to you properly. The stadiums and HUGE dishes which broadcast signals to satellite, then why was the signal being disrupted?
Same thing happened in some other cricket match, in another country (I don't remember where) and they said the same thing.
