Re: What to do with Coax braided shielding.
Compression connectors usually use the 1/4-1/4-1/4 method of stripping back.
1/4" of center tip exposed, 1/4" of dielectric, and 1/4" of outer sleeve outside the braiding.
The center tube slips over the dielectric and under the braid and is forced in a bit until the connector covers the exposed braid. Then crimp. Some also have a special pin to pre-crimp on the center conductor, but not all.
Then there's the old style that had you strip 1/4" of center and then 1/4" of outer braid, fold the braid back, slide the connector over and hex crimp it. That made the connector/braid connection and the center metal became the connector's pin. Those are still around the first one is more common now.
