I've had similar thoughts.  Whoever is willing to answer this question might
wish to suggest hanging vertical dipoles instead of requiring a ground
planes under the vertical elements.  Structurally, this would be a benefit.
Same questions apply.  Any takers?

Alright .. .the consensus was to go with a 4SQ (over a dipole 
at 175'). The dipole actually shows more gain and a lower 
angle (with gain) than the 4SQ BUT - and it is a big one - it 
has a strong lobe that is straight up so the qrm would 
be obnoxious)... 

anyway... several have suggested to use a center tower to 
support (via ropes) 4 verticals. This would place the tower 
at the center. How does this interact with the 4 verticals? 
Has any one modeled this and/or is there anecdotal 
evidence it does or does not work?
Also I assume the ground plane (I was thinking of 6 
elevated radials per vertical at minimum 8' above ground) 
would have a "hole" around the tower and not connect to it - correct?

[this would also apply to the folded back dipole systems - 
do they "see" the tower in a detrimental way as well?]
