Thanks to Wes, n7ws, I found out how easy it is to model a helical coil
with EZNEC. The following three antennas were modeled using the same
coil, 4.5 turns, 12 inch diameter, 10.8 inches long, using approximately
14 feet of wire. The antennas are similar. The frequencies are different
to illustrate three different arguments. EZNEC zero-impedance loads were
placed directly below and directly above the coil to ascertain the currents.
The accompanying .ez files can be downloaded and run on EZNEC if desired.


It certainly is interesting how a person who, only a short time ago was railing

against "the math model," suddenly gets religion when he thinks it agrees with
him. EZNEC not only uses math to reach its conclusions, that's *all* it uses,
plus
a few assumptions about how current is distributed over antenna segments.
Glad you've joined the fold, brother Moore.
