I wonder how can that be?
Everything known to man shows that with around 50 or 60 1/4
wave radials over any type of soil a system is out at the
very top of efficiency curves. Any Marconi vertical system
on any soil has reached well into the 90% range with just 50
or 60 radials.
A four square has 5-7dB gain over a single vertical of the
same construction.
I can't understand that unless someone has 400% antenna
efficiency. How would that happen?
