I've been playing with series-section transformers to go from 50 ohms
to 75 ohms and back (twelfth wave and now a wider bandwidth version
that's two stages of twelfth wave to an intermediate impedance) and
have been using F connectors and couplers at all the junctions (cheap,
fast to install, correct for the RG-6)
I have some RG-55 double shielded solid-center 50 ohm coax that I've
been using and installing RG-59 crimp connectors like you install a
compression connector on RG-6 quad shield... that is, leaving the
inner shield laid up against the dielectric and folding back the outer
shield and shoving the connector between them under the jacket, then
crimping.
The result seems pretty nice mechanically and electrically (the crimps
are a little ugly but solid)
But, eventually I'm going to run out of RG-55 and it's sort of
expensive and uncommon... so are there other 50 ohm cable + common F
connector combinations that have worked for anyone?
73,
Dan
