slykens - Thanks for the information. I am indeed in State College, so I guess I'll just have to suck it up and wait until next year (hopefully). I'll see if I can get any information out of the Comcast technician on Thursday.
mountiedog - I am located near Lemont, on the side of Mt. Nittany, above First Ave. I bought RCA bunny ears at Sears, which cost about $30. I'm not terribly tech savvy and I'm not at home now, so I don't know the equipment specs other than that. With this cheap indoor antenna, I can pick on digital signals for WATM (HD), WPSU (HD), WWCP, and WTAJ.
