I would not use a multi-band yagi on a band it was not designed for. That said, I would recommend you put a tribander yagi on the top of that tower. You can then hang dipoles for the WARC bands, as well as for 40/80m. You also might consider shunt-feeding the tower for 160/80m. I have an article on my blog on how I support 9 bands from one 50 foot tower: - A3S/A743 - supports 10/15/20m, and the dipole attachment for 40m. (http://boringhamradiopart.blogspot.com/2009/07/cushcraft-a3sa743.html) - homebrew trap dipole supports 12/17/30m. (http://boringhamradiopart.blogspot.com/2010/02/warc-trap-dipole.html) - Shunt feed with matching network supports 80/160m. (http://boringhamradiopart.blogspot.com/2009/04/shunt-feeding-short-tower-on-80-and.html) And here’s an article where I talk about the experience of using a tribander: http://boringhamradiopart.blogspot.com/2009/03/tribander-experience.html Bill Coleman, AA4LR, PP-ASEL Mail: [email protected] Quote: "Boot, you transistorized tormentor!
