[PLUG] cable modem and a distribution amp

[gyoza@comcast.net]

Has anyone experienced any benefit or problem after adding a cable 
distribution amp?  One thing I'm curious about is how the upstream 
signal is affected.  (I can't see what the upstream power level or noise 
looks like from the outside.) Everything seems normal so far.

(I added the amp because I plan to split the cable three ways soon.  Not 
likely, but possibly, four ways in the future.)

Below are the readings I took from my cable modem.

Connection    Signal/Noise (dB)    Downstream (dBmV)    Upstream (dBmV)

direct         38     2    43
2-way split    38    -3    45
4-way amp      34    11    45
