The best (and the ones we use) compress the entire base of the
connector evenly, creating a smooth crimp. The end of the coax is
evenly covered by the connector.

In the CATV industry, for F-connectors, isn't Snap-n-Seal now de the
norm?


Maybe for cable companies who are trying to be cheap. But the
professional integrators around here all use crimp-on. Not much more
expensive and saving one callback pays for a lot of connectors.

Snap-n-Seal certainly isn't trying to be cheap.
https://www.google.co.uk/#q=snap+and+seal
They enable an essentially watertight seal to be obtained without
distorting (or even scratching) the connector, and therefore have little
measurable effect on the impedance.

That's their claim, anyway.

And they are true!

As I said - none of the professional integrators around here use it

"Professional integrators" covers a multitude of sins. Professional in
what field?

. The distributors don't even carry it.

I suppose it depends which distributors you use. Such connectors are
hardly unknown in the USA.

In the UK cable TV industry, for most applications, it would be a
hanging offence not to use an approved Snap-N-Seal connector.
