Subject: [PLUG] cable modem and a distribution amp



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
