Which of these would work ok?
A pair of one of these Radio Shack a/v cables, I don't know the difference between the two... cable 1 cable 2
Or one of these RS RG-6 cables w/ some F-to-phono adapters... cable 3 cable 4 (the only one w/ specs)
Thanks for looking.
You can also look at www.milestek.com and look at part no. CA-1394-XXX where 'XXX' is the length in inches as they will custom make a cable for you. The cost is $12 plus $0.20/foot so that a 50 footer would be $22 and you would not need adapters and would have a good quality cable.
Why not use RS RG6 quad shield coax and some connectors. That is what I did and it works fine. I had a roll of the cable, so it cost me about $5 in connectors.
