Ok so I used to have tata sky connection couple of years ago, then I discontinued and went for SD Den Cable. Then, recently we bought a new 4k tv and connected it with the same den connection, but the picture quality was very bad. So I decided to upgrade to a HD connection, but the problem is Den doesn't has that feature in our area. So I decided to go back to tatasky and install an HD connection. So I wanted to ask how much will it cost me in total? I have the dish, it has LMB attached to it but don't know if it is working or not, have the wire too. Will it be better if I opt for a new connection instead?
