Do you have an HF Yagi on top of your tower?

Your BEST bet for 40M would be a rotary dipole of some sort,
such as a CC D40 on the mast above a High Band Yagi, or,
Match the BOOM of a high band Yagi as a rotary dipole on 40M.

I have posted my Boom Matching technique several times here 
on TowerTalk and it has also been published in the NCJ 
(National Contest Journal).  If you are interested, I can forward
a copy.
