I concur with Don's recommendation about using two dipoles on the same
feedline. I used this arrangement (with a third dipole for 20M) during my
Novice days and it worked well for me. The non-resonant dipoles aren't even
seen by the one your operating on. Just leave enough wire at the ends of
each dipole for trimming.
