Rule of thumb:
==============
5 foot might work if you are lucky, 10 should be okay, more is better.
SWAG:
=====
Model it and see how it looks.
OCD Award:
==========
Put up the 20, measure it (complex impedance if you can, SWR bandwith,
front to back ratio, front to side ratio, forward gain), log the
measurements, take it down. Repeat for the 15. Put them both up
together and see how much the things degrade. If too much, increase
the spacing and repeat as required.

I should have asked this when I asked the mast question. Lot going on with
this project.
What is the spacing to use between my 20 meter 4 element Cushcraft and my
5 element Hygain 15 meter. I have looked in every book and cannot find the
answer. I am sure this has to be a factor in deciding on mast also.
The bottom antenna will be at 73' if that matters.
Again please email direct to me to save bandwidth.
Hope this will be up soon and leave everyone alone.
73's Jim
