Modeling a 17 foot folded dipole made from copper #18 wire spaced at 2
inches at 14.2 MHz with EZNEC shows a feedpoint impedance of 46.1 +
j1893 ohms.



I didn't know I could model loops in EZNEC. But now I see that it has
problems only with small loops. I guess a 1/4-wave loop is not considered
small. I'll go back and try it.

My fall-back plan is to make a simple 1/4-wave resonant folded monopole and
feed it with a 1/4-wave length of 75 Ohm coax. There will probably be some
mismatch, but I think it will be tolerable.

Thanks, guys.

John
