I would just as soon put up one for "the low bands" and one for "the high bands." Or whatever. I figure the; /archives//html/Towertalk/2011-11/msg00249.html (7,223 bytes)

Some of the things you need to keep in mid to get a "good" base fed system inclu; /archives//html/Towertalk/2011-11/msg00255.html (10,161 bytes)

I think most of the time you are better off with a horizontal antenna . J; /archives//html/Towertalk/2011-11/msg00261.html (8,497 bytes)
