Shades of Owls and Spider Balls! This isn't a debate or just
opinions about things that are difficult to quantify.

The ARRL and Walt Maxwell (and several others) did the math,
and the math shows the coax doesn't do much except add a
little loss and very little bandwidth change over a regular
heavy wire dipole. Now I'm sure the Buzzoka would be wider
than a #20 copper wire, because the coax is much thicker and
has the same or more loss.

I actually measured two antennas, and the first time I saw
no difference at all (but I had poor test gear in 1975) and
the second time I measured within a few percent of what the
ARRL predicted (on lab grade equipment). If you read the
Handbook, consider their calculations as almost the same as
a real world test...because they are.
