Re: Contour installation this MondayMoCA can affect things that are running under 1 GHz as there are occasional harmonics that have negative effects... for instance here, I have frequently seen pixilated channels around the 777MHz range when the beacon power level is set too high (This is when the frequency being used is around 1200MHz and the device is limited to using the "D" band frequencies above 1150MHz)... two solutions for just about any device, put a filter on the device (assuming it doesn't need it, unlike WHDVR) or lower the power level... I usually will do both. Some devices may support a third option of fine tuning what frequency it is running, but that may make it affect other frequencies. Similarly this can affect modems if they are using the frequencies that are being affected.
Since "contour" is usually, if not always, professionally installed, a proper filter will be put in place particularly at the point of entry (that is why it is frequently called a POE filter) and you may get a few extra for other devices including modem and non-networked STBs (though I would probably wish to replace those since they generally cost the same)... I would probably state the concern about the modem and they should put a filter on it.
Personally I would probably have the modem connection split off as soon as it enters the house and then have the point of entry filter on the other split that leads to the splitter (or amplifier, though an amplifier usually also acts as a filter) that connects all the STBs however, if you keep the modem in the office and also expect TV there, that may not work but usually I have the modem in the wiring closet at the point of entry. |

Thanks for the answers from contributors to this thread. I've written down a few ideas from here and have another short list of things to check before the installer leaves tomorrow. At this point in time there won't be any MOCA client boxes in the house so that will make the install a little more straight forward.
Due to chronically low signal levels from the street my residential wiring has had a lot of attention from Cox to get things working here over the years. After the grounding block in the basement the RG-6 feedline goes into a 2 port splitter with one port connected to a straight run to the Motorola STB for the HDTV. The other port connects to a Cox installed SA preamp that has two 11dB output ports. One output port of the preamp connects to a straight run to the cable modem and the other port connects to three SD televisions in various parts of the house. Cox has installed numerous inline high-pass filters in the system as a preventive measure since I am a ham radio operator.
It has all worked fine for years and it also has no issues with my ham radio equipment which runs at power levels up to 1500 watts across the HF/VHF/UHF spectrum. Hopefully, the CISCO DVR STB will be as resistant to ingress (and egress) issues as my current Motorola STB. I'm always a little concerned about anything that has an external switching supply as the CISCO 6 tuner STB appears to have since they can be real RF noise makers across the spectrum. I guess I'll see tomorrow how it all turns out!
Thanks again,
