PL259 connectors serve as a good education that, in practice, you often can
get away with an awful lot of impedance bumps -- people who get a formal
education before playing with this sort of thing often get way too hung up on
any and all such bumps... and VSWR, for that matter! Smile

It looks like one of those horrible PL259/SO239 compatible things which
aren't really impedance matched to anything in particular. They're
probably ok for use up to a few tens of MHz, or for connecting up antennas
which are themselves already in need of a matching network. You might be
able to sell it to a CB radio enthusiast or a less discerning radio amateur
who doesn't yet know about N connectors.

It's an RG-59 quick connect to 50 Ohm RF. It allows one to use the
wrong size coax for a job meant typically for a bigger feed.

You screw it onto an RG-59 coax with the sheath removed (some) and
the ground shield folded back over the remaining sheath. That is what
the threads grab. There should be a needle shaped center jab
conductor in there as well, and that digs up into the center wire on
the coax. Solderless, and debatable as to reliability for anything
other then receiving.

At least it looks like the right size for RG-59.

What is it and why?

Maybe a right angle connector ? Either the dubious kind that threads
onto the coax braid directly, or missing a piece that threads into the
bit sticking out the side. Solder inner conductor into the centre pin
slot. Does that make sense ?

The sort of stuff that Amphenol is good at.
But no id or markings of any kind.
Heavy chrome-looking plating.

Picture an ordinary UHF 50 Ohm load, except no resistor and a pry-off
plastic cap. The inside end of the male pin is screwdriver slotted.

The pin rotates with physical resistance but does not have a screw or
threads or any other hardware associated with it.

Coming out the side is what looks like a 5/16 od x 1/2 inch long
internally threaded shaft spacer.

The threads may or may not be real threads (crimp retention?), and they
clearly just miss being either SMA or 1/4-20 compatible.

The slot on the male pin aligns with the center of the spacer.

Everything else is otherwise empty.

What is it and why?

How about some pictures on ABSE?
