Hello Folks,
The recent SMB vs SMX thread brought it up again: Suppose you must be in
a much lower cost bracket. I often use <gasp> RCA, even at 100MHz. They
work surprisingly well, especially if you terminate source and target so
a wee reflection won't hurt. However, lately they must have stiffened
the ground prongs and one client told me that they don't want them
anymore. Over there we had to resort to pliers to unplug RCAs, else the
fingers would become seriously calloussed.
So, what's out there for under 50 Cents a pop and (unlike BNC) easy to
mount onto RG174 and stuff like that? It doesn't have to be pretty or
shiny, it's all inside of systems.
Mini phone plugs/jacks should be fine at 100 MHz.
How about those coaxial, "power" types, like this?
(mind the wrap)

You might have to modify the plug and socket a bit, and impedance might be
interesting...
Cheers!
