What about your balun/choke connection?

W2DU choke, virtually lossless. The tuning cap is also virtually
lossless, much more so than a tuner with a coil.

The only real loss I have is the
loss of the feedline "213", and on 80m, it's about as good as ladder
line.

It's about as good as open-wire line with a 10:1 SWR. The matched line
losses in 100 ft. of RG-213 are higher than the unmatched line losses
in 100 ft. of open-wire line with a 10:1 SWR on 80m.

According to Wirebook II, the matched line loss for RG-213 is ten
times higher on 80m than the matched line loss for open-wire line.

If it were better, I could see it. But it's not. It's inferior.
If it were not, I would be using one here at the house.

You are so biased, you wouldn't use one if your life depended
on it. :-)

Why would
anyone want to do more work, for something a step in the wrong
direction?

It's a step in the right direction, Mark, toward an all-HF-band
antenna. I modified my G5RV yesterday to work well on all eight
HF bands plus 6m. Field strength measurements indicated it is
virtually identical to my 130 foot dipole on 80m.

The "average" storebought G5RV is
pitiful on 80m compared to the coax fed dipole.

Mine is virtually equal to a resonant dipole. Your "average" storebought
G5RV must be poorly designed - maybe lacking a balun - maybe using RG-58
coax - maybe using the wrong length of the series section transformer.

But everyone ignore what I say. I'm really fibbing, and just messing
with ole Cecils head...

I asked for some scientific proof of what you say. All you responded
with is prejudice and hand-waving. Please take time to calculate
the matched line losses in RG-213 Vs the unmatched line losses for
open-wire line and you will change your mind (if you are rational).
