Instructions for connecting a digital converter box can be found on the
MS Yahoo site under Files, 3rd item on list. This info is from Winegaard as an Excel file. It allows you to use the converter box to receive digital over-the-air signals, as well as use park cable &/or satellite easily. Newer TV sets that already are digital "ready" don't need a converter box. And, yes, if you have 2 TV's you'll need 2 converter boxes, if the TV's are analog.
