The splitter coming in the house is a three way unbalanced. The line in question was attached to the 7db I moved it to the 3.5 db leg. Now my modem reads -14.2 up and 48.5 down, a little better, and I am not getting the pixelization on the channels that I was.
Next I removed the splitter behind the tv a plugged the modem right into the cable from the wall, I now get -6.9 up and 44.7 down, big jump!
You suggested using a a dc-6 and amp, is it a bad idea to amp the modem line?
I am fairly new to this so please bear with me... I currently have -14 db losses (-3.5 3 way, -7 cable, -3.5 dc-6), if I put a 4 way in and make another run I will end up with -14 db (-7 4 way, -7 cable), if I make another run and add an amp like suggested I will get -10.5 to the modem and -0.5 to the tv (assuming 10 db amp).
Can someone suggest and decent budget amplifier? What amp I looking for in an amp, obviously gain but what frequency range?
The reason I was kind of dead set on quad shielded cable was because I tried purchasing shorter cables for behind my tv and my issue got much worse.
