From my experience, more folks should pay attention to the antenna and
balun work done by DJ0IP. They would likely have better performing
antennas. His work is proven on antennas and not text book or computer
models, but indeed he provides real world results.

In addition, Reg was designing in the era of valve output transmitters with
built-in pi-tank matching system, so, it was possible to match on different
bands. I'm sure mine worked across 80 to 10m in those days. For 80 to 10m
these days I use a off-centre-fed dipole with hybrid choke/transformer at the
feed point as designed by DJ0IP for minimum common mode current.

As I've already stated … I have a copy of the original Varney
RSGB article that describes the G5RV and plainly states that
it's a 20M only antenna.
Remember, it requires an antenna tuner …
Start with a dipole …
Keep the "magic" 32' length of 300 ohm feedline.
Delete the 68' of coax.
What's left? A "normal" open wire fed dipole, better
known as a Zepp.
