Well I took Kacz's advice and "invested" a big $4.00 for 2 F to RCA adapters at Radio Shack, and I must say the picture is sharper and colors better than the cable I was using. I have lots of various types of F type cables laying around in a box, so that part was free. I may experiment for fun and see if some other F type coax cables is better than others. Thanks, Kacz
