Now Reg, you know that most statements using the word
"never" are false. Here's a quote from G5RV, himself,
from "The G5RV Multiband Antenna ... Up-to-Date" in
The ARRL Antenna Compendium, Vol. 1.

"If you decide to use 300-ohm ribbon type feeder for
this (series) section, it is strongly recommended that
the type with 'windows' be used. ... Since the VF of
standard 300-ohm ribbon feeder is 0.82, the mechanical
length should be 28 ft. However, if 300-ohm ribbon with
windows is used, its VF will be almost that of open-wire
feeder, say 0.90, so its mechanical length should be
30.6 ft."

Now Cec, your reference to my use of the English language, which you
well understand, is an admission that you have lost the argument -
whatever that may be.

And you, more than most people, should realise that it's fatal to use
ARRL publications as Bibles.

The facts are, the Zo of the G5RV trannsmission line is indeterminate.
Everybody has a different but unknown value.

And it follows that, so are all the interminable discussions on the
subject which take place on this and other newsgroups. Hardly
educational. They approach amusing nonsense!

But no doubt you will wish to further dig yourself in and have the
last word. Go ahead! ;o) smiley
