Topband: (no subject)

[barockteer at aol.com]

I’m thinking about putting up a flag antenna for 160 and 80 meters. I 
had an idea that I might build the vertical sections out of some ¾ inch 
copper pipe I have lying around. The horizontal wires would be 14 ga. 
copperweld. I modeled this with 4nec2 and find that the increased 
diameter of the vertical sections results in a reduced feedpoint and 
termination impedance, down around 623 ohms, give or take. (This is for 
the bottom wire only 2 feet above ground).

Anyone have any ideas, comments, suggestions?
