Metric PL259?
 
Another contributor, "Jeff", has intimated that PL259's
are available in metric form.

Is this true?

If so, how does one find out which version of the SO239
is fitted to equipment?

Is the modern (say, more recent than 10 years old) Jap
gear fitted with these later plugs?

When one buys plugs and sockets from the rallies, which
ones is one getting?

Presumably there's no such thing as metric plugs in Yankland?

I recall buying a diamond dual band antenna and having to buy a metric pl
295 plug at the time so maybe there are two types.

Thanks for that, Walt - perhaps now is the time to scream
about "grey" imports if these were intended only for the internal
Japanese Market?

Unfortunately the Diamond colinear to replace the 5/8ths suffered
from the same problem, and the cable is jammed solidly onto the
antenna, so we may be stuck with it! I assumed that the lower part of the
SO239's screw thread was dirty and so drove the nut home with a
pair of pliers, assuming that this would clear the screw thread - we live
and learn!

I'm now well on the way to repairing the 5/8ths where I had to
engage in destructive test - I've been given a large sheet of
Paxolin/Tufnol which is 7/8ths of an inch thick, so 3 thicknesses
of that araldited together and turned down should do the
trick.

"Some cautions: Japan has a
UHF connector that has a slightly
different thread size than the standard
SO-239 (which has a 0.625-
24NEF-2A thread.) This metric
threaded connector is found on nonexport
Japanese ham equipment.
A PL-259 will fit on this connector,
but will only thread on for a few
turns leaving the shield connection
loose and creating an undesirable
condition. MCM sells a UHF bulkhead
connector (#27-220) with the
proper thread that replaces the
most common of these ******* connectors."

There are. Metric M4 PL259/SO39.

Don't know how you tell the difference other than
by trial and error. PLs don't usually have any
distinguishing markings.

Ho, Ho, Ho

Yet another fettling experiment that went wrong!
I'm so glad that I'm only a beginer, and not an expert like yourself...

The term "PL259" grew out of a military spec. You may have a metric
connector that _resembles_ a PL259 but it ain't a PL259.

I recommend for you a study scheme for the full Ham Radio
licence, because there is then a remote (because of your demonstrated
CBness below) chance that you will come across the gentlemanly
traditions of Ham Radio.

Stupid Boy.

It is standard practice when you have a tight/rusty
screw but neither the tap nor the die for the thread
to drive a nut against the corrosion.

Stupid boy.

It may be 'the standard' in your chicken shed but is most certainly not

the
done thing elsewhere!! I recommend a trip to your local library to

research
the concept of screw threads. Let me know how you get on....

Interesting - and answered in some of the less abusive postings
further down (thank you) - had the same experience, I bought a heap of
pre-made patch leads with PL259 plugs each end, but they wouldnt screw
down to all the so239 sockets in the workshop - didnt really think
about it, just put it down to lousy quality control (they were only $2
each) so binned them. Never knew there were two standards before.....

Been licenced since '87, am capable of 12wpm+ CW, been working in the
aerospace industry since '85. I forgive your misjudgements but must advise
you to stop signing off as 'Stupid Boy'. You're just a little 'restricted'
with your engineering intelligence but don't worry, it'll come with time. I
believe there are engineering newsgroups also avaialable to assist your
learning...

Do you wish to contribute to the discussion as a mature
Radio Ham and outline your procedure for the same
problem, or do you wish to be condemned forever
as a childish CBer sneering 'n' jeering from the sidelines?
