Over the years, immediately after a change in QTH, I have used the G5RV
as an interim antenna. My personal experience is that it is a reasonable
performer, as compared to a single band, resonant half-wave dipole, at
the same height, fed by the same coax/length.
While I certainly don't accept as Gospel everything that Tom W8JI
publishes, I generally find his work to be sound and educational.
How do you reconcile your position versus Tom's on this antenna?
I'll attempt to list the link here, but if it doesn't "take", just
search "W8JI G5RV". His hands-on A/B testing is interesting, along with
his modeling showing well less than 1db difference between the G5RV and
resonant half-wave dipole on 80 40 20, and within 1.5 db on 15. He
suggests a length ratio of roughly 80/20% versus the apparent standard
of 67/33%.
Like all antennas, construction, proximity to interfering objects, and
height make a huge difference in performance.
