Dan,
Not that is should matter that much (as a few % extra losses doesn't really
affect the S reading) but do you see and decay due to corrosion of the surface
of the wires?
I know that Al wires are less affected as AlO2 is non-conductive contra to CuO
that is a semiconductor. Needless to say Fe wires show higher losses as steel
is a bad conductor in it self and corrode heavily. I believe zink (as in
galvanized steel wires) is a lousy conductor too. Useful in Beverage antennas
though.
I, myself, am using insulated #14 OWL for my feed to an OCF dipole. As I have
my shack next to the tower I only have ~ 4 feet of horizontal runs.
73 de,

-:-
I doubt that the increase in efficiency of OWL over coax makes any perceptible
difference in signal strength at the other end of the QSO, but I still find
satisfaction in knowing I am not wasting that additional 5% of my RF power in
the transmission line, given that there must already be measurable losses in
the
transmitter tank circuit as well as in the ATU at the base of the tower. But
the
main advantage is knowing I won't have to replace the OWL every few years after
transmission line losses gradually creep up.
