Default Multi-band dipole question

Hello,

Just joined the group and I have a question about constructing a multi-
band dipole.

I plan to construct a 80/40/20/15 band multi-element dipole using
separate dipole wires for each band,
but a single feedpoint. My question is: how important is the spacing
BETWEEN the
individual band wires. I understand that they can't/shouldn't touch,
but is there any distance
that is optimal? or is just keeping them from touching enough?

Thanks,

Mike

There is a picture in most ARRL antenna books that shows a fan dipole
made from twin lead that just don't work!

Other than that, my experience with fans has been good. They are easy
to adapt to any environment. The same tactics adapt to a vertical
quarter wave as well.
