Not really a problem as it does not take many segments to represent the
ends, which has a slow change, as the center part with a more rapid
change.
If I were going to do it, I would use something like a spreadsheet
to plot the curve then draw straight line segments on the curve and
plug those directly into EZNEC.
The extreme case is modeling a loop as a geometric figure with straight
side.
EZNEC will generate loops with whatever number of sides you want and
thus it is fairly easy to see when increasing the number of sides
gives diminishing returns in the difference between the loops.
Hey, guys. Starting with a loop is a great idea! Make a loop and then
delete all but the wires that would closely resemble a catenary. What do
you think?
Except that a circle has a constant radius and a catenary has a constantly
changing radius.
Which means a circle would be close in the middle but crap at the ends.
A simple V would be close at the ends and crap in the middle.
