Tim:
Welcome to the reflector, one of the most informative in all of
Internet-dom (?)
As a Novice ham operator back in the 1760's, when we used to work late
night DX by candlelight, I had a three-band spiderweb antenna, which is what
we called the dipole you described. It had separate wires for 80, 40 and 20
(15M worked well on 40 without another wire set.) There was nothing special
about the design. (I didn't know enough at that time to think it wouldn't
work.)
My suggestion would be to install the antenna in the clear (as much as
you can arrange), and test it on the bands. Just make sure you provide a
bit of separation between/among all the dipoles. A foot or two at both ends
between each dipole should be sufficient. You can even spread them out
horizontally as well as vertically.
Once you get the antenna up, let us all know how well you're doing with
it.
