I am trying to use a crimp on connect with RG6 cable, but when I strip the shielding back I cannot get it to go into the connector very well. How much should I strip oh each. It said on the tool about 1/4 in for the copper and 1/4 in more for the shielding. I have tried this but I cannot get the shield into the connector, and I cannot get the copper exposed far enough.
It sounds like you may have a connector that is made for RG-59 coax, a thinner (and inferior) variety from RG-6. Get an RG-6 F-connector.
There are actually a range of diameter sizes for coax cable. As was said - you may be using RG59 connectors. Try to find a 'real' electronics store and take a cut piece of coax in with you so you can find the right connector. Companies like Belden have a connector-cross reference to help you get the right connectors. Also - Radio Shack sells a nice $5 T handle which you screw the connector onto so you can push the connector into the coax with a lot more force/ease.
