The wire is ordinary coax (RG6?), not quad shield (not that I know the difference, but I read the side of the wire, and it didn't say quad. I am trying to terminate wires that are in the wall, then connect to levitron quickport wallplates.
Are their tight tolerances in terms of how much of the coax to strip? Should clamping the compression tool be more violent? Do my tools suck? Do the brand of fittings suck?
A couple of pointers:
1. Make sure you have the right connector for the coax. Match Quad (4 shields) connectors with Quad coax. Match dual (2 shields) connectors with dual coax.
2. Make sure to prep the coax properly. roughly 1/4" to 3/8" of center conductor should stick out out of the white dielectric. 1/4" of foil on the dielectric should be exposed. All braid should be pulled back over the jacket so that all you see is the foil for roughly 1/4".
3. Make sure to seat the connector properly. The end of the white dielectric should be flush with the inside of the connector where the threading stops. If you look at the end of the connector, you should see a hole in the middle that is smaller than the threaded part of the connector. This is probably 1/4" from the very end of the connector.
4. Before you compress the connector, make sure you do not see any loose braid strands near the center conductor. If the connector is seated properly and you are looking at the end, you should see the silver from the connector on the outside, white dielectric in the middle, and the center conductor on the center.
5. Compress all the way. Make sure you are using a tool that is matched with your connector. Most compression tools are inter-changeable (in my experience), but some are not.
6. If you've done all this and you are still easily able to pull the connector off the coax, you may want to look for a different brand of connector.
Hope this helps,
