I got your point Mike
I shall upload a suitable diagram with jack more understandable.

It is the drawing of the jack that people are referring to, not
the positioning of the fuse!
The vertical bar would normally represent the sleeve - and you
have this connected to the fuse and on to +12v? Shouldn't the
sleeve and the tip be reversed in the diagram? Or do you normally
have the sleeve positive and the tip negative (some people do -
but most don't) in which case the diode is shown incorrectly!

Sarma surely responds.
The reverse protection diode has been shown in the ubitx
sch , both v3 and v4 perhaps.
I would only suggest that let us have a fuse in series to
dc of say 5 amps. the reverse diode would sit after the fuse
Any accidental reverse connection , the fuse would blow
and reverse voltage would not continue to the actual circuit,
once fuse blows.
