Default Cat 5 or Cable

In an earlier thread it was stated that Cat 5 or better should be run to all connection points prior to the U-Verse install. My question is this: I have good RG6 cable to all my TV sets and Cat 5e to all my hard wired PC's and I was going to make another another Cat 5e drop from the phone box outside to where I want my Gateway placed. Isn't cable still a superior transmission medium for video? I know that the newer 4 twisted pair cables (Cat5e and Cat6)have come a long way but shielded RG6 should still have an advantage for video. Am I all wet here or not? Thanks for the help.

you're not sending video, but rather a digital signal.

i'd take cat5 all day.

my 2 cents

I just believe the throughput and resistance to interference is superior in a shielded RG6 compared to a non-shielded phone line. Plus the fact I really don't want to drag my butt up in a Texas attic in July any longer than absolutely necessary. Does anyone know how much more will the tech charge me if I ask him to do it? I want this to go quickly once he is on site.

CAT5 and RG6 are both fine for Uverse. I can't tell the difference in video quality. And, a tech should run the wire any way you would like it.

Thanks everyone. I believe I'll stick with the RG6 since it is in great shape and already in place. My DTV DVR is wheezing in its final death throes as we speak so I am very psyched up about getting U-Verse.

And that may be just fine for you. But I'm not sure you understand the difference between U-verse and regular cable. The wiring between the RG and the DVR/STBs is an Ethernet LAN, the same as used for your computers. The RG and the DVR/STBs have the ability to work over either cat5 or RG6, but it is still an Ethernet LAN either way.

My setup has a cat5 from the RG to an Ethernet switch that feeds my DVR, a STB, 3 computers, a network hard drive and an ASUS media player.

You can use the LAN port on the DVR/STB as an Ethenet connection for your Blu-ray player or computer if you do use the RG6, but you could have some dropout issues because since the signal is digital the RG6 actually has less digital bandwidth than the cat5. If the signal were to be analog or RF the opposite would be the case which is what most people think. Interference is not an issue with digital like it would be with an RF signal.

I first had the DVR and STB wired by new RG6 that was pre-installed in the house and encountered some drop out issues when I hooked up the media player to the LAN port on my STB, so I switched everything to the cat5 by adding Ethernet switches.

Would it be in my best interest then to also run a Cat 5e drop to the location I plan place the DVR? That way I would have that connection between the Gateway and the DVR which will be with my HDTV. The remainder of my sets are SD so the RG6 wouldn't have to carry an HD signal. Also, they are on outside walls and those are usually bears to fish wire through. Again, thanks for all the help.

I would because in the future if you add a Blu-ray player or other device that uses the LAN, you will be set.

Default Just my opinion

HI ALL , just get some CAT 6 and be done. No issues with bandwidth. Got mine from ebay for cheap and they work with no issues. The 2 techs that put in the network said that the best way to go; because of future programing. or http://www.monoprice.com/products/se...s&keyword=cat6

Ran Cat5e from AT&T outside box to Gateway and from Gateway to DVR box. Also pulled his RG6 from Gateway to outside splitter and left the existing RG6 in place to the remaining SD sets. The installer said I saved myself around $170 for doing all the attic work myself so it was definitely worth it. So far I am loving the service. Some of the HD may not quite as sharp as DTV but it is more than acceptable to my eyes. I watch my locals with an antenna and nothing really matches that picture anyway.

Ethernet is almost always better than coax in all but one respect. The overall distance limitation (as perscribed by the computing industry) is around 100 ft. You can get ethernet to go further than that but you will risk some reliability issues. The coax has better range over the long haul but all of the connections in the network have to be to a higher standard than is normally practised by your average cable or satellite company, as a rule. Remember that the cat5 connections between your gateway and your receivers are essentially ethernet connections. This is different than the connection between your gateway and the NID (outside telephone box). The homerun connection is just making use of the twisted wiring inside the cat5 cable. It is the general consensus among almost all of the Uverse terchnicians that a cat5 homerun is superior to a coax homerun in almost all circumstances. The amount of twist in the wiring actually tends to protect the vdsl signal from environmental interference much better than the shielding on the coax cable. The only time I think coax is better is in the rare case where your house is actually too close (within a few hundred feet) to the crossbox. In these rare cases, the coax will provide more resistance inside the line (75 ohms to be exact) than the cat5 will.

Sorry to come to the party late, but just to make sure I understand:

I can connect the Gateway to the DVR using 75 ohm coax and free up a cat5 port.

TIA

Yes if you have the DVR being fed via a coax, the ethernet port is free to connect another device and the receiver essentially becomes a switch.
