| reply to dehmmy Re: [CATV] Trouble with Splitter and Pixelation
said by dehmmy :coax in >--[3-way unbalanced splitter]--> [1 to each room and cable modem in the -3.5dB slot] I did something similar a while after we had an addition put on the house and had issues with the new drops:
Before:
RCN | 4x-splitter (-7dB) | | | | | CM (2 HD DVRs) | 4x-splitter (-7dB) | | | | | (1 QAM, 2 SDTVs) | 4x-splitter (-7dB) | | | | (2 SDTVs, 2 unused drops)
After:
RCN | Surge Protector | 2x-splitter (-3.5dB) | | | | CM Amp (+15db) | 16x-splitter (-15dB)
[unused ports on the splitter, as well as unused drops capped with 75 ohm terminators]
TVs off that last splitter were getting snowy (especially in the MBR where we split again for a ReplayTV...). And one of the TVs with a QAM tuner had trouble with a few top-end channels.
After I redid things, I did noticed at first I had some pixelation with the HD-DVR boxes, but then I realized I hadn't put in the filters RCN had on the digital lines before I changed it up (I'll have to look at what they are when I get home).
After the new configuration, everything is clear all around. CM has better signal strengths than it did before and no snow anywhere... |
