In the Antenna Conpendium volumn 2, page 106, there is a "Fat Dipole",
by Robert C. Wilson. In the table it claims a bandwidth of 500 kHz on
80 meters (no mention of what the SWR is for that bandwidth). In the
text he says the SWR is less than 1.6 from 3.5 to 4 MHz. EZNEC says the
2 to 1 SWR bandwidth at 50 ft height and no feedline is 240 KHz. That
antenna is just two parallel wires (total length of 118 ft), both
driven, separated by 3 ft, not connected at the ends.
Here is an antenna that will give you all of 80 meters under 2 to 1 SWR:
