Some better numbers for RG6a/u: Freq Atten MHz -dB 10 0.8 50 1.4 100 2.9 200 4.3 400 6.4 1000 11.0 The CATV band is approximately 50 to 800MHz. With 200ft of cable, you should see 2.8 to 16dB of loss. While there may be problem at the high channels, all the lower channels should work. Any idea where channel 428 would be in that frequency range? That's a duplicate of 4,2 but in HD, and it works when 42 doesn't. I believe that's entirely up to the cable company, you'd have to ask an engineer there. http://en.wikipedia.org/wiki/Digital_cable Quote "For example, a cable company might call channel 5-1 "channel 732" and channel 5-2 "channel 733"". The 4 way splitter has a loss of about -7dB. Just a point. I may not have made it clear. I had the tech put in two 2way splitters and connect me to the first one. Hoping to gain 3db. (or 4) and it did make a difference. Where does the other leg of that splitter go to? And is that end properly terminated? [...] -- Regards, Joerg http://www.analogconsultants.com/ |

Why would there be a reflection in a closed cable run? |

You must be a mere ****ing cable installer. Bwuahahahahahahaahahahahahahaa! You and the KiethKeithStain are nothing more than mental masturbating dumb****s. Yer gonna get TARred and feathered, K0 boy. Nice to have amusing idiots back again. And I am way above your paygrade. But that is obvious to anyone that graduated any grade, even first, which you obviously have not. tom K0TAR |

I know about "cable trash" cable installers that used to go around to different cities, working for different cable companies. I know what corners they cut, and what responsibilities they shirk off. I know the difference between them and me. It is way below my pay grade and way above YOURS. Compared to you, I am the FADM, and you don't even rate 4-F. Take your stupidity back to your left hand, putz! I post-wired thousands of ports, and that was over 30 years ago, you ****ing retarded twit. I have done 350' runs through the woods when they were unable to get the hard line trucks into the area. That's what happens when the Bengals GM has his house all the way back in the corner of an Indian Hills cul de sac. Mr Brown was a big dude too. There were deep wear tracks in his carpet where the big ****er roamed. Outside the tracks, it looked new. Did lots of pre-wire too. Worked for General Instrument for the first year I was out here in Ca as well. That was almost twenty years ago, asswipe. I was performing instruction for them by the time I left. The gear FEEDS the cable companies, AND the broadcasters. You lose. As usual... again. |

My remarks were about the ****tards all around me, not myself. I actually learned about what things one does NOT do as a cable installer, and cutting corners on policy was high on the list. Makes me wonder why anyone would have ever paid a retarded presumptuous asswipe like you, if you cannot even read a simple Usenet post. |
