Besides being commerical advertising in a non-commercial newsgroup,
some of the Wi-Fi Plus antennas are bogus.
Duz anything on this page look like a "pattern"? It does say
"patterns". Where are they?

What the hell is "effective penetrating gain" and dBmp? This reeks of
invented hype.
What are the dots on the pattern at:

Usually, they mean that someone measured those data points. I've done
LOTS of antenna pattern measurements and I've never seen anything so
close to perfect. Did anyone actually measure those patterns and why
such a tiny graph? If the front to back is really 40dB, why doesn't
it show on the graphs? 100MHz bandwidth, at what return loss? VSWR
graphs? Any side by side tests with conventional antennas to
demonstrate the alleged superiority in NLOS and "reduced noise"?
Here are what real patterns should look like:
