Just picked up my live tv and it looses signal with the small antenna. I still have the original coax wires running from my tv to the roof and hooked up to a dish network dish on the roof that we no longer pay for. I tried hooking it up to my boxee to see if I would get any channels and nothing. Would I be able to replace the dish on the roof with an antenna to get better reception and would it work with the boxee. Any thoughts or suggestions?
