Roy and Tom,

Thank you. I actually tried that as one experiment. The loads window showed the
connection as you described. When the antenna is configured close to what I
expect there is a resonance near the intended frequency. So that is progress.
Now I am just trying to tweak the parameters.

On the SWR scan is there a way to print or plot the step outputs? I am trying to
determine the resonance point.

Thanks,
Dan

To add to Tom's excellent explanation, let me add that you only need one
wire to model the vertical. I suggest beginning with the Vert1.ez
example antenna to get an idea of how it works. Look at the model with
the View Antenna display. Then specify a load in wire 1, 50% of the way
from end 1. The load will appear in the View Antenna display as a little
square. The Loads Window (where you specified the load) will show that
the actual position is 55% of the way from end 1, which is the closest
EZNEC could place it with the specified number of wire segments. If you
change the number of segments to an odd number, EZNEC will be able to
place the load exactly at the middle. You can specify other positions in
the same fashion, but it might require more segments to get it really
close to where you want.

Source and load positions are specified in exactly the same way.

All,

I am trying to model a loaded vertical using EZNEC. It is fairly easy
to start with the vertical model and extend or shorten it. I also
think I created a load correctly. However I seem unable to connect the
load to the vertical segment. How can that connection be verified?

Also, what type of also load supports a second connection to a second
wire to simulate a mid load?

Thanks,
Dan
