I had not heard that different metals are more or less effective at RF
shielding at higher frequencies. I had heard of Mu metal that's used in audio
recording studios to specifically block 60Hz hum.
I tried to find info about what attenuation different materials offer and all I
could find was
This is only to the NTIA. The government agency that's handling a lot of
the stimulus grants. How else will they be sure that an area doesn't
already have coverage?
This is, in my not so humble opinion, a reasonable use for the data. It
would have been better if the NTIA had asked the FCC
This is, in my not so humble opinion, a reasonable use for the data.

grant application :-)
I appreciate your 'forward' thinking.

Plastic next to the antennas??? CRAZY! So the radios pretty much talk to

True. Hopefully in the next few weeks we will see the fodder fall to the

I know some special purpose plastic enclosures made for RF work have
conductive/shielding qualities to them. There's even conductive/shielding paint
one can buy for RF projects. So those plastic boxes might not be as bad as you
think.

I have several Trango AP's and 2 Mikrotik backhauls on a water tank. I
am making some upgrades to one of the backhaul links (better wireless
card). I head up to the top of the tank, take out my laptop, plug it in
to the switch up there and boot up. I

What did you do to fix it? Looks to me like your laptop or the switch
caused the problem.
Wireless card in the laptop doesn't transmit unless it's acting as an AP,

OR... the laptop was radiating strong spurious RF energy and that
spurious energy was interfering with the receiving ability of your
backhauls.

You left your p2p client running on your laptop from the night before,

After looking at a lot of the stuff you guys guessed, I next suspected
my cell phone. Shut it off, no changes.
Then out of desparation I unplugged the laptop and shut if off. After
about 45 seconds, things cleaned up.

Not sure I buy that. Platinum is the best conductor, then gold, then

There are private weather radar systems that live around 5600 MHz as

What a web we weave! It all goes back to the money. If they didnt offer the
