Your phase delays and magnitudes may differ. You must model the antenna to get this close.
Later I will suggest a way to optimize the antenna over your ground conditions and mutual
coupling conditions.
See pattern plots below to view pattern differences using the same system, same ground but with
the improved phasing angles. Remember this is normalized to show gain over a single same
type vertical.
We have increased the gain by .66 dB and the front to back radio by 6 dB or more!
This can
be easily achieved with your controller by adjusting the 90 degree network for a 111 degree
phase shift and the adding 44 degrees to the 180 degree phase line.
