At risk of being called a Troll, and having little else to do at
present, I copy from another newsgroup the following text.

"The effect of an impedance mis-match at a coaxial connector of
ordinary dimensions is practically zero at frequencies up to UHF.

Regardless of its other dimensions, the primary requirement of a
mismatched connector is that its length should be appreciably less
than 1/4-wavelength at the highest working frequency.

People are unnecessarily worried at VHF and below. Mix up 50 and
75-ohm connectors, and indeed connectors of unknown Zo, and carry on
regardless.

For an analysis of performance, download in a few seconds and run
immediately program CONNECT from website below."

Program CONNECT will calculate the effect on performance of inserting
any relatively short length of line, of Zo different from system Zo,
into the system. It's less than the inexperienced might imagine from
reading frightening magazine and handbook articles about impedance and
conjugate mis-matches.

If you have a short length of coax lying around, of unknown Zo, just
use it!
