Re: [PLUG] cable modem and a distribution amp

Hmm.  I read that digital signals could be lower than analog signals.  0 
dBmV being ideal for analog TV.

Do you know what the signal strength difference is now?  (My amp is +8 
dB per outlet.)

I had Internet trouble recently, before the amp was added.  I don't 
think the problem was on my end.  But, I do see a new problem with the 
amp in place.  There is some video noise; a faint vertical pattern at a 
slight angle creating a cross hatch on some channels.
