DISH has the manuals on their website - Look for "Hopper" under Quick Reference and Receiver Manuals. http://www.mydish.com/Support/manuals Correct. You will need a separate antenna feed to the TV (TV signals cannot be combined with the DISH Hopper feeds). Correct ... three tuners in a Hopper is a limitation. Many users in our forum have chosen to get two Hoppers in order to keep their tuner count up. The shared PTA tuner may help in the evening if two or more of the TVs had people wanting to watch major network programming. DISH advertises it as "six tuners" and it can serve that way if you accept four tuners are the major networks (ABC, CBS, NBC, FOX). I'm looking forward to seeing how OTA is integrated.
