I know that SO239s do not have their metal connection "buried" as deeply
inside as female 115 VAC power sockets do, so don't furnish as much
protection from contact with a "hot" lead.  Still, how and/or why did we
depart from the power cord convention, when it would at least provide
some visual warning of a "hot" lead?

>>RF is different.  You can't get a shock from it.  You can get a
"burn," but you can get that by contacting a safely connected antenna,
including a mobile whip, directly from the antenna anyway -- so why
protect it elsewhere?

Also, cable-end females were never specified by the radio guide standard
(mil spec) for UHF type connectors (difficult design), only males were
(and panel mount/couplings/bulkheads for females).  Not certain why, but
might be because the weakness of that design is mostly in the female
receptacle, not in the male plug.

You can get cable-end female (and mil spec) connectors in Type N and
other designs.
