5/8x24 thread PL259 vs metric 16x1mm thread
I came across info about missmatched PL259 from Aliexpress with a metric thread, almost fits but not quite
No personnal experience and never seen HF gear especially old Yaesu equipment that doesn't use a standard SO-239
My FT980 does use the standard fitting for a PL259
