Default Any experience with the G5RV multiband wire antenna?

Of course, implementations will have slight differences in actual
feedpoint impedances, and the outcome is very sensitive to slight
differences in feedpoint Z. This "no-tuner" matching scheme will
probably need significant customisation for each implementation.


==========================================
The World-famous G5RV.
---------------------------------
What everyone appears to forget, is that Zo of the balanced twin-line
section, on all bands except at 14.15 MHz, has a considerable affect
on feedpoint impedances, swr, losses, etc.

When describing systems and performance nobody ever mentions what Zo
of the feedline actually is. Omission of Zo reduces any following
discussion to blythe, innocent nonsense.

R.L.Varney himself never gave a value to Zo. He didn't need to. He was
concerned mainly with 14.15 MHz. It would be unfair to accuse him of
not understanding the serious effects of Zo on other bands.
