The clarity of Airtel digital TV is good but I think that it is very much expensive. It has a monthly plan if 650 and didn't offers all the channels still. Though it has HD channels but other service providers also have HD channels and they didn't cost that much high.
It also has recording capability but this company also charges for it. When we were installing it the service men said that it would run in heavy rainfall but I don't. We have tested it many times. It says to remove obstacles from the dish.
