Point the Nanostation at SCZ, San Jose, or Loma Prieta and see if it can

Hello Jeff,
In preparation to resite the antenna with a stronger bracket in a
different location that doesn't have a steel plate in the wall, I just
ran three noise level tests - one pointed at the city of San Jose, the
other at cube at Mount Umunhum - and the third at Loma Prieta.
I set the preference on the top graph to 'show channel usage' (whatever
that means). And I set the bottom graph to 'show more channels'.
Here is the noise level with the antenna pointed at San Jose:

All I can make out is that the noise to San Jose and to Mount Umunhum are
about the same - while the noise to Loma Prieta is different.
I'm not sure what the AirView "channel usage" tells us - but they sure
are 'perty graphs. It would be nice to see what everyone else is getting
in their neighborhood by way of RF noise.
