This should be no surprize to those who read carefully the W2DU
articles and also read the experiments conducted by W7EL and
reported in Antenna Compendium #1 dealing with measurements of RF
on the feedline.

I use a bead balun when I make measurements with my General Radio
1606 RF bridge. I have recorded differences between measurements
with and without the beads; the ones with the beads are closer to
expected values.
