The rush was that I wanted to get back there today and hookup my AppleTV and the new coax. It is a freaking pain-in-the-ass to get back there and I won't trouble you with the details. I ordered the cable from Amazon on my phone while I was out shopping. Should have it tomorrow. My question above about needing an antenna has been answered. I found an AM antenna in my box o' electronic junk and now RF works. As to the difference between digital and non-digital coax, the digital ones have the phono style connectors for one. Not sure about other differences.
