Under downstream signal the channel power is currently -0.5dBmV, the SNR is 34.565.
Before the cable upgrade it used to run -8 to -10 for downstream dBmV.
Under upstream signal the channel power is 38.5dBmV
The cable attaches to the house, runs approximately 70' to the garage, then I have the first splitter - one leg for the cable modem and one for the tv signals. The first splitter is a Channel Vision HS-2 and it's about 20 feet from that splitter to the cable modem. All the coax is RG6 CommScope Quad Shiled with purple T&B Snap-n-Seal ends.
Input from the cable company hookup on the corner of the house to the first splitter is about 70 feet.
short - I'm using a metal coupler for that, from that splitter to: Drop 1 (upstairs living room) is about 10 feet (the coax comes in and down the garage wall and the living room is on the other side of the wall). Drop 2 (downstairs family room) is about 25 feet. Drop 3 (downstairs bedroom) is about 10 feet. Drop 4 (upstairs master bedroom) is about 35 feet. Drop 5 (upstairs spare bedroom) is about 25 feet. Drop 6 (upstairs bedroom) is about 30 feet. (output of tap is terminated)
These are approximate. I actually measured everything a while back but I've misplaced the paper right now.
Yep, I got that - makes perfect sense too!
A little later today I'm going to play a little - maybe try some attenuators on the output of the amp (I dug up a 10 and a 3, 13 overall should allow me to turn the gain back up about 3/4 way), maybe try hooking to the test port (btw, that test port and the input test port are unterminated right now, should they be terminated?). I also have a motorola 15db amp I may try in place of the Channel Vision one.
Thanks Ed, Take Care,
