I have 100ft (30m) tower that will have a 3 el 40M yagi and 80M rotatable 
dipole on it. I am going to put up another tower (probably 70 feet, maybe 80 
feet) for a log periodic array for 30-10M and probably a 6M yagi above log. I 
am also thinking of trying to feed the 100 foot tower for 160M. I do not recall 
seeing any discussions on spacing of towers. As far apart as possible is 
probably the best advice of course. These are guyed towers so the guys will 
dictate some amount of spacing. Any pointers to discussions about tower 
spacing? Facts? Opinions (humble or otherwise)?

I had thought about maybe trying to space them and feed them as array but I 
don't think I have enough room for a 2 el 160 array with an appropriate ground 
field. The towers will probably be in exactly a North-South configuration which 
is not optimum for most places from here (Europe is about 45 degrees, Asia 
closer at about 345 degrees, VK/ZL at 240 degrees,  Africa at 90-110 degrees, 
and South America/Carribean about 150-200 degrees). I have not tried modeling 
two different top-loaded towers yet (looks hard at the moment). I need to spend 
some time with ON4UN's book but any thoughts on the array scheme would be
