It will not work on two bands without a trap

Barry's designs use a loading coil in each leg rather than a trap, and 
the coils are roughly at the point where the insulator would be for a 
half wave on the higher band. Then the coils, and a bit more wire.  The 
160/80 version is roughly 160 ft long, the 80/40 version is a bit under 
100 ft.
