[TowerTalk] 15 Meter and 40 Meter on the same tower?

[john at kk9a.com]

What 40m beam?  If it has shortened elements it is probably not resonant on 
15m and I would not expect a problem.  I have a 2el 40m Optibeam about 15' 
below one of my homebrew 5el 15m beams and I do not see any interaction.

I have a 135 ft rotating tower.
I am wanting to put a 5 element 15 meter beamon a 36 ft boom
and a 3 element 40 meter beam on a 46 ftboom on the same tower.

How much space is need between them? Or is this just not a good idea to
start with?
