[TowerTalk] Tower spacing

[Pete Smith]

If you can get hold of it, there was a series of articles in NCJ a few 
years ago by K3NA that did some sophisticated modeling of inter-tower 
interactions.  I don't recall if he came up with some generalizations 
that might be helpful to you.

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)?

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 welcome.
