He's confusing the operation of a single band loop, to
your planned all band operation. If single band, I would
prefer his method. If all band, I would prefer yours. The only
downside
to the 300 ohm line is it gets pretty lossy when wet. But 450 ladder
line with
"windows" would cure most of that problem. On the upper freq's
with a high SWR, the 300 ohm line would have less loss than coax.
On VHF/UHF, the difference is drastic. If you feed a TV antenna with
rg-6
coax and balun, you will have a good bit more loss than using 300 ohm
line.
On UHF the difference will be fairly huge. But expect a blackout when
it
rains hard. The local ATV machine would turn to snow. Once the rain
quit, it would gradually come back. :/ If you are working all bands,
and
using a tuner, there is no reason whatsoever to tune or match the
antenna to
the line. Waste of time...
