Hi Peter,
Well, my point was not to criticize NP4A antennas, but to tell that you cannot
draw conclusions with only one measurement.
Also, no "real antenna" is perfectly omni-directional and it can show an
unexpected "notch" in the radiation diagram in one particular direction while
having a "positive" gain in another direction.
73,
Yan.
