Many thanks to the Guy's testing DVD'S and posting results for the rest of us. Now, I ask myself , I wish they could test cables and put to rest the question of whats better. I read on another site, that "One piece of test equipment can test both freq response and return loss. A RF network analyzer." can actually do this anyone with this unit who would like to test a sample of maybe the ten top cable sugestions and report back? or would this really work?
