High noise - recommendation on what attenuator I should get

High noise - recommendation on what attenuator I should get

I'm about to upgrade from double play to quad play, and am looking at what you fine folks would recommend give I've recently re-wired much of my house.

 

I used to have RG6 to each room (6 total), with each of them terminating in the CommScope 9-port device. However with the remodel I removed the RG6 cables and put CAT6A in their place running a new RG6 Quad shied cable to the one TV. *I realize I might regret removing the RG6 in the future*

 

My questions

 

(1) - what splitter should I used knowing I only use one TV point and one Internet?

(2) - what attenuator should I get to help with the voltage issues? 3db or 6db?

 

Here are the modem stats if that helps?  I'll need a Docsis 3.1 modem to get the Gig speeds.

Re: High noise - recommendation on what attenuator I should get

You don't need to attenuate those downstream power levels unless you are actually experiencing problems.

 

Why do you think that you have "high noise" ? The SNR's are o/k. There are no uncorrectable errors.

Re: High noise - recommendation on what attenuator I should get

I think when I said High Noise, I meant the Downstream Power levels for some of the channles are higher than the recommended +10dBmV (albeit barely). 

 

Downstream Power Levels: -8dBmV to  +10dBmV

 

What splitter would you recommend for internet and TV only? Do I still need the MOCA filter for the incoming RG6?

 

Thanks

This one is very good;

Only if you are using / have MoCA devices on your coax line.
