[Connection] Do my signals look ok?I just did a home-run install with new rg-6 ran from the box outside to each room. Im currently using this drop amp » smile.amazon.com/gp/prod ··· F8&psc=1I took a pic of the signal page, I think this is the right page its the only one that I could find dbmV levels . I have a xg1-a X1 dvr box. everything seems to be working fine I do get some pixelation every now and then |

Your downstream receive is coming in pretty hot. You're 10 dBmV out of spec.. |

do you think its cause of the 4dB boost from the drop amp. Should I ditch the amp and use a passive splitter ? |

I would be wary of what that will do to your upstream. Basically upstream and downstream have a reverse correlation, when downstream goes down upstream goes up. If you try it and your upstream power stays comfortably below 50 dBmV (I would say 47-48 is as high as I would be comfortable with) then that would be fine. A better solution would be a forward path attenuator (which is pretty difficult to come by in the US as a consumer..) which will reduce your downstream receive without affecting upstream. |

What happens when the downstream is 10dbmV high? |

So do you think I should a 10dB Attenuator I found some on amazon like this one » www.amazon.com/EMRSS-SMA ··· 5&sr=1-1or » www.amazon.com/Parts-Exp ··· e_text_z |

Just put the cable which goes to your modem at the "MODEM OUT -4dB" and post results again. You probably don't need the signal to the internet modem amplififed, you probably need a service truck roll to fix the pixelation issues you are having with your cable tv. Make note of the channels you have the pixelation on, and let the tech know. They will be able to troubleshoot where the problem is coming from and fix it.
In 99% of cases a drop amp is a band-aid solution.
I suspect if you do as I suggest you'll see the downstream drop to about 12dBmv and upstream to about 30. The upstream should be a bit higher, but that's for the cable company to address, not you. However, if you moved it to the -4db and got 12/30 you could reasonably add a 6db pad (attenuator) and it would bring your signal levels to around d/s 6db u/s 36db & in spec, or if you put 10db to 2dbm d/s & 40db u/s. |

said by josjohnson:What happens when the downstream is 10dbmV high? If downstream is too high on internet you can get errors on the modem for downloads. If downstream is too high on your digital boxes you'd get pixelation or black screen on those channels. If you didn't have pixelation before installing the drop amp, then your signal is too high. Or it was too low before, and now too high because you chose a drop amp which amplified so much. Do you actually have 7 or 8 tv's connected in your house? |

No right now i'm only using 2 ports living rm and master bed rm and then the cable modem is on the modem port already.. I think I got it for more than what I needed, the other 2 bed rooms and office I have both have tv's but I don't have a box for them. |

youd be better off with just a plain jane splitter. |

Please don't start more than one thread about the same issue. You already had one here |
