Sorry, don't know what you mean - the 239/259
is not a standard for some antennae? Is that what you
are trying to say?

No,

you will find that there are 2 different threads available,
quite a few 'white stick' antennas use a metric thread.
A non-metric thread plug will screw on most of the way
and then jam, leaving the centre of the plug free to
rotate. Solution buy a plug with the correct thread.
