Answers to your doubts in bold text below:
2. my doubt i have videocon dth and the disk anteena is fixed and i dont want to move the anteena or else i unable to watch the paid channels
so can i use it without disturbing the anteena ?
You can get a separate dish antenna, LNB and set-top box to view free-to-air channels. Its better not to disturb Videocon d2h and get a separate fta setup.
3. Can we watch paid videcon channels and this free channels at a same time ( or we have to remove the satellite finder for watching the paid videocon channel ? )
No Videocon box cannot save Free channels.
4. and what about rain it will damage i think ?
This is not to be used in rains. Also after finding signals, the sat finder is disconnected.
and plz name all good free best channels u received ?
I received Zee Punjabi, Star Utsav, B4U Movies, MH1 and many more channels. Will post screenshot later.
