Topband: Help with RFI

[Pete Smith N4ZR]

I would seriously consider going wireless.  A few years ago I had a 
direct strike on the top of my tower. Fortunately, everything was 
disconnected, so I sustained no damage in the shack.  In fact, the only 
significant damage was to two computers on a cabled Ethernet network, 
both of which showed physical signs of damage at and near the Ethernet 
port.  It was clear to me that induced current from the strike, picked 
up by the Ethernet cable, was responsible.  I switched our house over to 
wireless networking and have been completely satisfied.  It doesn't hurt 
that it all operates at UHF.

73, Pete N4ZR
