     Yes, Michael, you have misunderstood.   Regarding external-source 
communications signals, I said that the metal mesh will serve as shielding.
     The issue with the mesh does not involve EMR from communications 
signals, but high frequency ground currents and electrical pollution that comes in 
with the utility-provided   60 Hz and is also generated on site by our own 
high-frequency producing electronics.   Metal mesh does indeed present an 
"attractive" path to the low-voltage but high frequency currents.
     Please understand that when I refer to these as high frequency, I mean 
high relative to 60 Hz.   As I said, the bigger part of the pollution is about 
25 KHz.   The GS filters filter up to 100 KHz.
