I got mine to work although I did burn through about 6-8 connectors before I figured it out. Remember how hard you have to jam the damn coax into the f-connectors? Well, you have to do the same thing to the RCA cables. I found it helps a lot to take the screw-in part that goes in the crimper and put it on the end of the RCA connector when you are holding it in your hand trying to jam the coax into the connector. You want to strip down to the conductor about 1/4" - 5/16", and the jacket gets stripped the same amount (assuming you are using the stripper tool from PartsExpress too - man does that thing work!). It doesn't hurt to then *carefully* use a razor blade to strip off an additional 1/8" of jacket on the cable to make it easier to jam into the connector. I seem to remember that folding the braid back didn't seem to help much, though you would think that it should. Its also pretty important to be using the right connector (e.g. the Quad connectors for quad shield, and regular RG-6 connectors for something like Belden 1694.) My last comment - yeah those directions &$*@ sucked - cost me about 15 bucks worth of wasted connectors.
