Using EZNEC 2.0, I model a one-wavelength wire at 50 feet above real ground
("normal"), and feed it at 50% from one end. I get a pattern that has nulls off
the ends of the wire. If I change the feed point to 25% from that same end,
the pattern has nulls off the sides ("normal" to the axis) of the wire.
I didn't realize changing where an element is fed would alter its radiation
pattern.
I am plotting the "total" field in an azimuthal plot.
I'd appreciate someone explaining why this happens or pointing me to some
readily-available reference material.
Thanks,
Bert, N4CW/1
