What method do you use to prevent the trim screws from backing
themselves out? I don't see any safety wire or other obvious means in
the photographs.


This is temporarry install havent herd of them backing out I do use a dab of
locktight


The lead out is high voltage automotive spark plug wire connected to the
antenna.


Of course, that high-tension lead has a copper conductor in it, not
the noise-suppression type with graphite impregnated cotton cord (or
whatever it is), right?


Yes copper plug wire out the fuselage.
