put up the longest dipole you can as high as you can and load it with a
tuner... that is the easiest and fastest way. if you have an 80m dipole
that will work ok to try it out.

Unless you have a legal-limit tuner, or are going to use QRP power levels, I
would advise against that.
If the dipole is coax fed and is 80M 1/2 wavelength, at 100 watts out there
is going to be some crazy-high RF voltages inside that tuner. If it's an MFJ
300 watt tuner, more than likely it's going to arc like a welder.
Feeding the dipole with ladder-line is a different story......

I am in a city lot and use an Alpha Delta DX-A sloper.... but again it helps
to have a tower with a tribander to act as a capacity hat....
