Question, does the magnitude of feedline radiation from the OCF

There shouldn't be any feedline radiationn, this is oan antenna
running coax to a 4:1 balun at the feedpoint.

Hi Mike,

Not all 4:1 BalUns exhibit enough (or sometimes any) common mode Z.

Okay. Perhaps I might better characterize my experiment as a comparison
of a vertical and an OCF dipole of indeterminate vertical vs horizontal
performance. I was under the impression from the designers of this
flavor of dipole that they were not radiating from the feedline unless
you wanted that "feature". In that case you would feed the antenna with
balanced line. Certainly the antenna doesn't seem to be radiating RF
from anywhere but the antenna bits.

p.s. forgive the spelling, I am using a beta of Thunderbird for my
newsgroups, and it seems to have a few quirks that make it hard to see
what I have written!!
