Thanks to Kevin Loughin (KB9RLW) and his friend Jim (AC9EZ) for this intriguing answer to large SWR swings found on dipoles trying to cover the entire 80 meter Amateur Radio band.

According to Kevin and Jim, a modified fan dipole with elements cut for both the 80 and 75 meter segments of the band will provide low SWR across the entire 75/80 meter band.  Using 450 ohm ladder line and a good antenna transmatch (i.e. "tuner") are keys to making this antenna attain maximum efficiency.  A good, simple antenna that will provide wide 80 meter coverage at a reasonable cost.
