I have a four in line vertical array for 80 meters that is in
construction. The verticals are .25 wavelength long and the seperation
is .25 wavelength. Each has 50 .25 wavelength radials.
I have measured all the self impedances and the coupling iimpedances
and from that I have calculated the mutual impedances and the driving
point impedances.
The driving point Z are as follows:
Vertical 1 13  j17.2
Vertical 2 17.5 + j5.7
Vertical 3 36.4 + j21.5
Vertical 4 80.4 + 60.5
I have seen numbers for a 3 in line array but no field values for a 4 in
line array. I was wondering if any one has built and
measured/calculated the Driving point Z so I could see if I was in the
ball park.
