You will find this method described in any good wire antenna book.

A simple dipole with an antenna tuner will cover the entire band just fine.

Most Hams who have used wire antennas on 80 & 75 meters have.
If you want a real versatile dipole feed it with open wire through a tuner,
a decent tuner
will allow you run about everything you want from 3.5 - 30 MHz.
