You are talking about substituting discrete wires to create the effect of a
loop made of 10 or 100 mm pipe. Just do that in the model and see what
happens.

Subject: [Antennaware] Antenna wire in EZNEC
Hello Guys,
I have a model for loop antenna. I have noticed that if I increase the wire
diam. from 0.5mm to say 12mm for a 20m circumfrence wire loop antenna the
1.1MHz gain goes up from -28dBi to -13dBi. Increasing the diam. again to 100mm
the gain is now -5dBi.
Is the increase in gain due to lower wire resistance or a reduction in the
loop inductance or both?
Can I use say 300 Ohm ribbon ( wires in parallel ) to get the same results as
12mm diam wire. Also can I use two wires spaced 100mm to simulate a 100mm diam
wire?
