Ive been installing tvs & rooftoop arials for sum 32yrs. Check out LI-HDTV.COM. The only way to receive all HD channels is by using the best equipment installed topside.Depending on your area of L.I.will depend on what equipment will be used. I have tried & trued packages available. Plus I'm working on a package that will include TIVO-ROKU. Cant wait.
