Re: Airport quality levels?

Hi all,

I am now geting the same values as you, being around 1.5 - 2m away from
the base station.

Something that should be avoided: hanging the base staion onto a
vertical surface with Apple's bracket. This reduced receive level by 10
dB for me!

I suppose the problem lies in the polarization of the electromagnetic
waves, which would in that case be different, hence non-aligned, and
greatly reduce receive levels. I'll have to open up the base station and
see in what position they mounted the antenna ;-)

Cheers

Michel
