>>> Cut the antenna to about 3675 kHz and verify that it resonates there. Connect a half-wave of any good 50 ohm coax to the antenna, then add a quarter-wave of a good 75 ohm coax. If the combined length is too long, coil up the excess. If you need more coax to get to the rig, add any length of 50 ohm coax.

AutoEZ users:  If you'd like to experiment with modeling this
broad-band 80m dipole see the 4th section on this page:

There is a link to download an AutoEZ format (.weq) model at the end
of the section.
