Hmmm. 40M is not very wide (only 4.2%, as compared to 80M which is 
14.3%). What kind of antenna is it? Simple antennas without traps or 
loading coils like resonant dipoles and verticals typically cover 40M 
with SWR below 2:1 if tuned to the center of the band.

80M is the tough one, but can be tamed with some transmission line and 
or stub tricks.
