Bob,
There is an article on a website by John Tate EI7BA on his experience
with building a quad. One of the things that he did was to add a folded
bent 40m dipole to one side of the quad. It is explained on his website.
It looks pretty neat. The link to that page is
http://www.iol.ie/~bravo/Cubical%20Quad.htm . Maybe this will help you
or give you some ideas.

Subject: [TowerTalk] QUAD FEEDING
I'm ready to put a Lightning Bolt 2 element, 20/15/10m quad up at 80ft.
I
want to do this right the first time, and get the best reasonable
performance from the antenna. Lightning Bolt supplies a 2:1 balun for a
common feedpoint. The owner of the company sez this is the best way to
feed
the antenna for max performance, anyone who sez otherwise is wrong.
But...he
can't supply figures or pattern pics. Others favor the gamma match
method,
but still I haven't seen any concrete evidence that this is the best
way.
(believe me, I've scoured the web)(feed line)is just no good; the only
way to go is seperate feedlines for
each band. Still no facts or figures to back up this claim. I am
primarily
concerned with maximum forward gain and a fairly good pattern. I won't
quibble over .5-1.0 db or so. If it makes any difference, I am also
interested in integrating a 3 element 6 meter quad on the same boom.
(seperate feed) and/or mounting a loaded 40 mete
r dipole along the boom of the quad. So, who has the facts? Please, no
educated guesses or second hand anectdotes. Thanks.
