Wrong wrong wrong
When Lou designed the G5RV coaxial cable wasn't available to the amateur.
His system was designed to work on the then six major ham bands, in conjunction with a particular LC network for tuning.
The introduction of coax at a later stage introduced a level of imbalance.
He came to our local radio club some years ago where he went through the design process and practical implementation of his design.

Not necessarily true. Strictly speaking, a half wave dipole is a
ballanced antenna. Although somewhat a different design than the
original g5rv, those you buy today use the ballanced line as a sort of
tuning stub, and most state you should run at least 50 feet of 50 ohm
coax to the radio. I ran one like that for years and it worked great.
I also once ran a double sized one that worked fine on 160 Antenna
lengths were doubled as well as the tuning stub.
