Just moved into a house near Trenton with a gigantic antenna on the roof (three-story house -- don't know how old the antenna is, but it looks pretty old). Hooking up a regular TV to it, and I get pretty good reception on the usual Philadelphia stations (3,6,10,12) (the antenna is pointed right at Philly, AFAICT).
Anyway, I then hooked up my Samsung SIR-T451 and get... nothing. It shows 'No signal' all across the board. I don't have another antenna to use at the moment, but I am certain the Samsung is fully operational.
Does this make any sense at all? What may be the problem here?
