So,EZNEC models "very far away" and, in my example, the channel 23

saying that is my main confusion.

Hi Pat,

You can use the "near field" table to then build a second antenna
(representing your own at the proper distance) with a load, and then
look at the power developed to that load to see how things perform.
This goes beyond the normal use, but for those who will slog through
it, there's a way.

Thanks again, Richard. I just purchased an EZNEC license so I will
try that to further my learning. (I had been using the demo version).
