See
those two little lights? They indicate voltage and current
on the "transmission line", the two parallel copper
pipes they're sitting on. As Bill adjusts the antenna at the end,
and adds inductors,
capacitors and stubs to "tune" the line, you see exactly what's
happening by
watching those lights (and the usual meters and scopes). And he can
slide the lights along the line so you see how the SWR changes (or
doesn't) anywhere along the line.
Another light on
a receiving antenna shows what matters most - how your received
signal is affected by all the manipulation. Bill explains it all
as he demonstrates. It's the best way you'll ever "see" VSWR...
