It has been discussed, and modeled, and discussed some more, and modeled
several different ways... the results always seem the same, the loss in the
coils and shortness of the elements makes the gain from adding the third
element so small that its not worth it. Try searching back a few years, or
more than a few, in the towertalk and antennas reflector archives and you'll
probably find this a few times. My recommendation is to put one on top of
the tower and rotate it, then put the other one half way down and fix it to
the south or whatever other direction you might want to switch to quickly...
or just save the second one for spare parts.

Subject: [TowerTalk] 40 meter antenna project
OK guys, I'm getting ready to get my tower back up and I have two Cushcraft
40-2CD antennas. There is no way I will be able to stack them but I would
like to consider making a three-element antenna by lengthening the boom. Has
anyone ever done this? If so please tell me where I might find the info.
Thanks,
Gary - N5KDA
