From My Opinion there is no problem if you used Other DTH antenna & wire , it's a problem from Satellite setting end !
Means Technician should not set TS Satellite Perfectly !
If You have normal FTA STB then pls Blind Scane in it & you got result !
I think tata pq and sound q is better then d2h. When I bought lcd I saw toshibha lcd with tata sky good sound. But I bought d2h. And pq and sound not good. But I have no metter other things because I choose d2h only for sudarshan news channel
When I was purchessing. Shop me m tunes channel lagakar toshibha me tata sky use kiya tha. I saw good pq and sound in tata sky with toshiba lcd. But not good sound in d2h
