For years, I had an inverted vee for 40m that had what I remember as "W9INN 
coils" on the ends.  Close-wound on 10 inches or so of ~1" OD PVC, they 
provided a significant lump of inductance.  Pigtails about 4 feet long 
outside the coils resonated the antenna to frequency on 80m, while the 40m 
resonance was only slightly changed.  Since the antenna was about half size 
on 80, the 2:1 SWR bandwidth was only about 75 KHz, but it worked OK on 80 
and FB on 40.

I bought the coils commercially, but that was ~30 years ago -- they would 
be easy enough to homebrew.
