@bellsouth.net | I assume RG6 for in-home cabling? I've never had Comcast at my home before and I'm about to order it for Internet only. I assume all cabling from the outside of my house to the cable modem location should be RG6. Am I correct? | |

We don't usually install quad shield. My office doesn't even use it unless it's already in a house. A good RG6 will work fine. We can even make 59 work if it's in good shape. Otherwise, it gets replaced if we can.
2. I do installs all the time that are free, 19.99, or 29.99 depending on the promotion and house wiring.
Hope that helps the OP.

| Re: I assume RG6 for in-home cabling? All very helpful. I have DirecTV for my television and will be keeping it because I have a weekend getaway with a satellite dish - I just carry my receiver from one house to the other. So I'll be keeping my DirecTV which uses my existing in-home cabling.
I'm just going to run a single RG6 cable directly from the outside of my house where Comcast will terminate over to the location inside the house where the cable modem will be. Won't be a big deal - I'm pretty good at cabling and I don't have to worry about anyone falling through my attic other than myself. | |

| If you have RG59 installed in the walls, that will usually work. (Some houses, for whatever reason, were prewired with RG59, mostly those built between about 1985 and 1995). If you do have existing RG59, Comcast will probably use it, especially if it's prewired (installed in the walls when the house was under construction). | |

| Quad shield is mainly needed in settings with lots of electrical interference. In the vast majority of home settings, the extra expense of RG6-QS is usually overkill. But RG6 without the QS is not overkill compared to RG59. RG59 was designed for 60 channel analog cable TV. You don't need to replace RG59 with RG6 if you already have RG59 and you're getting a solid, no-dropout signal everywhere. But if you're having signal quality issues particularly with digital and HD cable TV and HSI, and you have an older RG59 installation, it becomes a leading suspect as at least part of the problem. Replacing it with new RG6 may solve your issue. If you're installing new, now, the savings benefit of using RG59 over RG6 is not worth it, IMO. RG6 is a better match for today's HSI, digital, and HD cable signal from Comcast. | |

| Re: I assume RG6 for in-home cabling? I would and have gone with RG6QS
rember the cable can ether be an investment or a hinderance
if you have RG59 then it might work might now and down the line will likely cause problems
if you have RG6 its fine for now but you never know when they start upstream channel bonding they may need to lower the noise and QS might be needed then
next in 5 ormore years (maybe less at the rate things are going) some tech might need even beter so then RG11 might end up being needed
if your going to rewire your house go with the best reasonable cable (RG6QS) (RG11 is currently super overkill) | |

Most homes don't need it yet, but then, most didn't need RG6 25 years ago when everybody was installing RG59 for 60 channel analog cable TV. | |

@videotron.ca
| You don't install RG-11 in a regular house. RG-11 is use for very long service drop (150'-300') from the pole to the house. There's no difference in signal strength between 75' of RG-6 and 75' of RG-11. We will only see a lower lost on higher frequencies when the cable drop is very long, not on short distance.
Connectors are bigger and difficult ton install behind a wall plate, it's really overkill for 75'. | |

| All cable has a percent loss per foot
with RG6 its lower than RG59
RG6QS even lower
and RG11 even lower
the common use of this is that with less loss per foot you can run it a longer distance
when you use RG11 in a place where RG59 could work then the loss is simpily so low because of the distance that its not currently enough to make a differance
and it is currently super overkill for 98% of cable runs
maybe in 10-20 years we'll get to the point that the loss on RG6QS is enough to cause a problem but at the same time in 20 years we might have left copper in the dust | |

| One other minor issue: length. Short runs of RG59 should be OK, especially for hookups from the wall to equipment. The longer it is, the more attenuation you will get at the higher frequencies.
It may also depend on your area. Some areas are still only 750 or even 650MHz. It's more of an issue for 850MHz or the rare 1GHz areas. | |

RG11overkill
@videotron.ca | Probably, depending of the signal strength at the pole and the local cable system operator's policy. | |

| Re: I assume RG6 for in-home cabling? I don't know how it is in other regions, but its Comcast's policy in my region to use ONLY rg6qd. It's also our policy to proactively replace any rg59 cabling in any home that we come across. The shielding on rg59 is far from adequate and allows all too much ingress/egress.(I swear rg59 works better as an antenna than a cable) When we have our FCC fly overs, that's the number one thing that causes signal leakage from residential homes.
You get some handy-man-jack-do-yourself'er that decides to use cheap rg59 coax with badly crimped f-connectors and radio shack splitters, then all of a sudden the whole neighborhood is having ingress problems.
In short, rg6 and rg6qd seems to work pretty good for your average joe household. Going beyond that tends to be overkill...atleast at this point in time. Who knows in 5 years... | |

| Re: I assume RG6 for in-home cabling? said by metal80772 :The shielding on rg59 is far from adequate and allows all too much ingress/egress. That really depends on the RG59 you're talking about. RG59 intended for CCTV systems typically only has a copper braid and no foil. R59 intended for CATV systems has an aluminum braid and foil.
I would make no assumptions about the ingress/egress performance on a cable described only as "RG59", since that doesn't tell me what the shield construction is. | |

| Re: I assume RG6 for in-home cabling? which is why the standard is there
if someone says RG59 then who knows but if they say RG6 then you know its adequate
its what do you expect if you see the standard on the cable
RG59=replcase (unless you want to inspect it fully)
RG6= likely happy with it
RG6QS=very happy might just replace then ends if they are hex crimped or a do-it yourself job
RG11=you know money was spent and a pro likely installed it | |

The RG6 designation tells you NOTHING about the type of shield it has. I've seen RG6 that consisted of nothing but a foil shield and a few wires, not even a full braid. (This garbage was sold by Radio Shack in the early 90s as pre-assembled cable).
About all you can conclude from an RG6 designation is that the cable has an 18AWG center conductor and 75 ohm impedance.
There is no standards body that defines what an RG6 cable is. RG6 is an old military specification that the military no longer uses. It is not like Cat5E where there is a defined performance criteria that cable must meet.
In fact, some cable manufacturers like Commscope don't even use the term RG6 to describe their cables (they use the term "Series 6" instead), and others use terms like "RG6-type". | |

| I agree about making assumptions(especially about RG6), but I was generalizing for sake of argument. In any sort, the majority of people that have rg59 in their homes, is a pretty fair bet that the shield construction is insufficient. Hence, the company that I work for, has created a policy to eliminate that from the system. | |

Maybe it depends on what your system was using back then (and how far back "back then" was...in this case it's no earlier than about 1984, which is when Manassas got wired for cable), but around here *most* of the RG59-type cable I've seen was installed by Cablevision of Manassas, and what they installed was Commscope or TFC CATV drop cable which has a 67% braid and a bonded foil shield. Many older houses around here still have RG59 from the pole to the house. | |

| Re: I assume RG6 for in-home cabling? If you go back far enough (to the mid-70s) the typical RG59-type cable that was being installed had only a copper braid (I don't believe the technology to make an aluminum braid existed then). Many of the cable systems in the Pittsburgh area have been active since the late 60s, according to the FCC. It seems reasonable to assume that the RG59-type they installed in the late 60s and through the 70s is not up to the standards of the RG59-type that Cablevision of Manassas started installing in 1984. Prior to 1984, pretty much everything was wired with twinlead in this area. I lived in a house built in '83 that was pre-wired with twinlead!
So, perhaps, due to the age of the cable the system you are on is requiring the replacement of the RG59 type cable, some of which could reasonably be expected to be 40 years old. We don't have that problem here because the only entity that was installing RG59-type cable in any significant amount was Cablevision of Manassas and they started late enough that the technology to make a good shielded RG59 cable was already available. | |
