I would start with modeling a single vertical dipole. Once that is
complete and you can plot the pattern and SWR you can add elements. EZNEC
will not optimize so you have to manually change your model to get the
desired pattern. I believe that there is a 40m vertical dipole here which
is easy to scale to 80m by changing the frequency:

I just downloaded EZNEC and am not good with it at all. I am trying to
plot a
vertical 3 element beam on 80 meters. A center vertical dipole with a
reflector
and director spaced 50 ft apart and feed with 175 ft of lmr 400 anyone
willing
to walk me through it so I can see the gain and fb ratio?
