You can model this, and all variations easily with EZNEC available
online (and is within the limitations of its free use).

I'll look at it and see. I tried the free version but it wouldn't install
with Crossover Pro (I don't use Windows) and I may have to install VMWare
first.
=======================
Probably another Linux user . Roy ,please note ,there might be an
emerging market for a Linux version of EZNEC.
