I have own dish tv set-top box since last 5+ years . in starting it provide well service but after warranty ended 1 year the network range becoming poor and more poor . the charges for channels is costly than other . if problem occur they sent their technician to set the problem but they charge 200 rupees per visit and the problem is solved only for temporary they just move the direction of the antena and nothong .
We can also do this by checking singal frequency on tv and move it . nowdays the channels are less provided but the charges are same .they always solve it as mention above .network range is poor really poor
