Directv receiver for OTA broadcast
I am looking for an OTA receiver. I see the 'Direct TV' boxes made by RCA and Hughes for $40 (open box) to $99, have an 'antenna' input. Would this work as a digital receiver for me (I don't want the directv part). This would be cheaper than the Walmart $200 receiver (which I just bought to try out, and works pretty well for a novice like me). Will the receiver decode HD and send out a composite signal my TV will undertand (as SD).
Thanks in advance for you opinions
