Well it is not legal in qatar, however, for viewing some indian DTH here are the few choices

1) Install a 8 feet parabolic dish with Prime focus lnb, and you can view all channels from Big TV HD

2) normal big dish for Airtel

3) this works best in States , but can try it is called a sling box, install one on your home town and one here, and the program gets streamed and you need only internet connection here

Hope this helps
