Hi Fred.

Have you actually tried to load the dipoles with a tuner yet?  If one of 
the dipoles is a 80 meter one, I would expect it to work quite well.  If 
your lowest band is 40 meters, then that is another matter -- you'll 
probably have a hard time getting it to load, but the 5th harmonic of 80 
meters, as I pointed out falls very close to 17 meters, and would work much 
the same way as a 40 meter dipole works on 15 meters, depending upon where 
in the 80 meter band it resonates.  I also wonder if it would be practical 
to load a 17 meter hamstick against the tower.  That would probably be 
about as lightweight as you can get, and there is a lot of metal in the 
tower -- it should approximate the performance of a shortened vertical dipole.
