Re: FIOS singal loss
said by ramslt8  :it was based on rf loss in general not on moca loss, and it came from a formula that i was given during my fios video training class, of course it is a mute point since anything over 150ft should be run with rg11 to avoid problem such as this. ps. i also said it was an "estimate" an "estimate" would suggest a ballpark figure or appoximation. making a blanket statement that "rg6 attenuates -14dB at 250 ft is just false.
imo, you ought to reconsider what you've learned in your fios video training class. understand that verizon training material is flaky at best, and add to it that most of the training courses are taught by contractors that are just parroting something from a binder.
if you've been through many vz courses or wasted your life on a netlearn module, i'm sure you already know this. |

If your not having a tiling problem on normal broadcast TV then you can completely forget about an amp. Even the new amps that Vz has do not amp moca, they simply bypass it. First I would question the splitters used to make sure they are 1ghz. Also the way you have the splitters configured, while it may be helping the rf signal to the work shop, it is actually hurting your moca signal. How far is the router from the splitter? The moca lan signal has to go through all the resitance of both splitters to get to the shop stb. First thing I would try is a 3way to a 4way split and put the router and shop on the first splitter. If that doesn't work, try moving the router closer to the splitters.
The moca transfer rates can be checked from the stb Diag screen under hma or home connected status. |

said by ramslt8 :estimated signal loss for rg6 @ 250 feet is aprox 14db that's an incomplete statement. do you mean the loss on RG11 in the MoCA range is 14dB? Otherwise, you're incorrect.
loss will vary at different frequencies. the loss at about 350Mhz on rg6 at 250 is probably in the 14dB range, but verizon uses frequencies over 1Ghz for MoCA.
the loss in the moca range is something on the order of 25dB on rg6. |

said by muelleski :Does anyone know of a good 2 way booster that will work? I dont really want Verizon in my work shop I have some priceless cars that I would rather a stranger not know about. I heard that the PDI and the Motorola both work. I did put the STB on another line in the house and its fine, I doubt the line is bad as its brand new w/ good connectors. I not too familiar w/ db loss but I thought by splitting it immediately than boosting it would helps. Also would it help to put a Drop Amp or 2 way booster on each end of the run or is that overkill? Should I be boosting the modem as well as the run to the shop? a friend who works in the industry found this but has no experience with it » www.cabletvamps.com/Products/EDA-FT08100.htm. any further help on this would be great. you need to read the posts about the MOCA signal or do some research. this is the issue at hand concerning your guide and vod. regular cable amps corrupt the moca signal. they can only be used in conjunction with a moca NID.
if all of this is greek to you, it's time to buck up and let vz take care of it.
and no disrespect to your "car collection", but unless you're hiding dead bodies or a massive grow operation, most techs wouldn't be slightly phased by what you have.
anyone who's spent even a short amount of time in the field working in people's homes have seen so much crazy stuff that it doesn't even phase most of us. |

said by centc408 :Sounds like your cable is bad. Instead of using two splitters why not just make the first one 6 outs? no no. You'll never make it 250 feet after the 12dB loss of a 6 way or splitter.
I hope you used rg11. |

have you tried checking your signal level either in the self diagnostics with guide version 1.6 or on the diagnostics screen when you press menu, select, select for older guides?
if you have 1.6, the self diagnostics will also show if you have an ip address, which would tell you if the moca signal is getting through. |

for some reason this never came to my email acct. I have a bunch of stuff to try now, thanks for the input. I ran the run myself afterward but it is an RG6Q run. |

As was already asked what cable are you using. MOCA runs around a gigahertz. Standard RG6 has near 7 dB loss at 1GHZ per hundred feet. At 250' that's close to 18dB + 3.5 for the splitter. If your router is plugged into the other splitter that about 13 dB loss. So you are looking at ~34 dB loss.
Yikes! |

The reason that the box in the shop does not have guide or vod is because somthing is blocking the ip from the router. All of the above is ip based...if you buy an aftermarket booster it will not let the two way traffic needed to provide those features..if it is a signal issue then you need to contact verizon. they now have passive 2 way amps. Try unplugging all boxes, turn off router, and plug that box in first. So it will be the first to gain an ip. The integrity of the line and possible existing cable comp filters could also be a problem...try removing the two way at the start and barreling the lines together where the 2way once was. That will gain you +3.5 dbs..good luck |

try eliminating all splitters except for 1. move the router next to the tv you were having a problem with and see if it works. If it works you need a booster on that leg. If it doesn't then there is a problem with the wire. |

What type of cable rg6 or r59? did a verizon tech install that run if so did they test the levels? A regular booster/AMP will not work to give you a guide vod or widgets as the moca needs as amp capable of reverse traffic have vz come back out test the leg and install the correct amp if needed.
There maybe a cost associated with the truck roll if you did the run yourself but you will get the amp and hook up correctly done for free. |

take the STB from the shop and try it on a run in your house that you know works correctly. If it works fine in your house you know it is the run.
I think some STB's tell signal levels, i wonder if yours does? Hopefully the run isnt damanged at all? |

| Ok I have FIOS installed and I have an HD DVR box that is on a long home run from my work shop (over 250ft) to the FIOS hub. I have the signal split from the initial line to a two way, then from the two way I have the one long run, and the other side going to a 5 way splitter w/ 4 lines going out to TV's and the last to the router. All work except the long run to the shop. that run I have TV but no menu, on demand, etc. Any suggestions on a booster or change in setup? I tried a couple powered boosters from radio shack but none have helped. I have read that the motorola booster will hlep but wanted to ask the experts 1st. |
