[Moon-net] H frame interaction

[Earl (Jim) Shaffer, WB9UWA]

Hi Wilt.

The interaction of the vertical members of an H frame on the vertical
side of the array can be substantial and will degrade gain and pattern
to something between moderate and severe unless it is handled properly.
I believe GM4JJJ did his properly. Here is his web site:
