[Antennaware] Antenna wire in EZNEC

[Guy Olinger, K2AV]

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.

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?
