What is odd though, I haven't seen any corrected errors in your test results. If there were any errors to be corrected, they should first show in corrected errors, which is why I asked you before if you had corrected and uncorrected reversed. So, I'm wondering is it that the Roamio tuner is not able to correct any errors, and all errors become uncorrected. Or is it that it is able to correct some errors, but it is not showing how many?

I have some questions regarding the grounding. You linked to a grounding block but I found some I wandered would also work that I can get cheaper and quicker:
http://www.amazon.com/cable-Coaxial-...rounding+block http://www.amazon.com/PcConnectTM-F-...rounding+block http://www.amazon.com/CNE41312-F-Pin...rounding+block As far as actually, checking it and ensuring everything is properly grounded is this something a handyman could do? If so, is there something concise that I could give to him and say this is what I need done. Another question is whether I would need anything else other than one grounding block? |
Any of those three would be suitable. Note that the first one is an add-on item. Watch the shipping costs. I ordered an item listed on Amazon, but not sold directly by them. The seller said free shipping in the listing, but it wasn't free and he refused to refund shipping costs. I told Amazon I considered that a breach of contract so Amazon made up the difference by giving me a credit on my next item if sold by Amazon, which they did.
A talented handyman could do it if you show him the diagrams I posted, otherwise you need an electrician. The biggest problem is the connection to the house electrical system ground. He must not disconnect the house ground to connect your grounding block and mast ground wires, even for a moment. He should use a split bolt which makes it possible to connect your ground wires to the house electrical system ground. Quote:

ANTENNA MOUNTING 1

I don't have a photo of your antennas, so I'm trying to picture in my mind if you have both antennas on the same mast, and which is on top. I looked at some other map images to try to see how high your antennas might be, but I couldn't tell. My concern is whether the signals coming from the NE for the C2V are able to clear the roof of the house that is East of your house, because when I turn on the green signal lines for the interactive map, they cross the peak of the roof of that house.

ANTENNA MOUNTING 2
When I was looking at the satellite map of your house on bing.com, I was able to rotate the bird's eye view to see the rear of your house. It is an old image (2011), so there might have been some changes. These are the options I see: 1. A 5 ft tripod mount at the peak of the roof at the rear of the house. 2. A thru-the-roof mast to your attic at the same location, similar to a plumbing vent pipe. Both of these options would require roof penetration, which would need to be done with care to prevent roof leaks. 3. A mast at the back of your house that would run from the first floor deck up to above the peak of the roof. Its base would be on the deck. It would be fastened with an eave mount at the top, and several wall brackets below. It would allow you to adjust the aim of the 91XG from below using the "Armstrong method" before tightening the U bolts. You could move just the 91XG first and leave the C2V in its present location for now. This would allow you to try other antennas there more easily. The 91XG has a tilt feature which would allow you to tilt the front of the antenna up for higher angle incoming signals like your 2Edge Fox signal on CH 49. Your location is at the right end of the profile: http://forum.tvfool.com/attachment.p...1&d=1416102509 Channel 49 is 683 MHz center frequency. Note the increased gain and more narrow angle at that frequency, which means the aim is more critical. Also note the notch at each side of the peak, which means a loss of gain at that angle. http://forum.tvfool.com/attachment.p...1&d=1416102879 If you stay within the FCC height limits for your antenna, any neighbor or HOA that complained would have to prove that you weren't in compliance.

Rabbit,
I was looking at this link: http://www.erico.com/public/library/fep/LT1476.pdf Particularly, the second page and I believe I have that on the side of my house. When it is daylight tomorrow, i can check but just looking at the pictures on the second page I believe it to at least look pretty similar to what I have. Is it safe for me to assume that you have your 91XG and C2V on the satellite mount that is located where the teardrop indicator is located on the satellite view of your house? It looks like it is on the East side of your house, about half way back from the front. I don't have a photo of your antennas, so I'm trying to picture in my mind if you have both antennas on the same mast, and which is on top. I looked at some other map images to try to see how high your antennas might be, but I couldn't tell. My concern is whether the signals coming from the NE for the C2V are able to clear the roof of the house that is East of your house, because when I turn on the green signal lines for the interactive map, they cross the peak of the roof of that house. Both antennas are using existing satellite mounts that were there already. The coordinates I gave you were pretty close to the area where both antennas are mounting. There is no mast in use that I am aware; just the satellite mounts. |

I've tried to upload some photos I took with my IPAD of the electrical system outside the house and the placement of the antennas. The pictures aren't the best but hopefully will do. The 91XG should be easy to make out and the C2V is just to the right of it in the photo. |
Thanks for the photos; they help.
Pic 1: Left to Right, that looks like telephone, power, and internet. Is that correct? I don't see an IBTB. Pic 2 & 3: I see the 91XG, but not the C2V. I'm confused about the location. I thought the antennas were on the east side of your house. It looks like you were on the east side when you took the photo and the antennas are on the west side. Maybe I have the wrong house. |

Regarding pic 1 from left to right, it is internet, power, phone. You may need to rotate the photo. Looks like you are right regarding the IBTB. |
When you connected the antenna directly to the TV, it didn't seem to have any trouble with the signals, but both DVRs did. That tells me that the TV tuner can tolerate less-than-perfect signals which the DVR tuners are not able to do because they are more particular and fussy about the signals than the TV.
In earlier testing, yes I believe I found that to be the case. Ranking them I would put TV, Tivo Roamio, DVR+. The Roamio was a clear step above the DVR+ in the tuner category (and feature category for that matter). Tivo support isn't going to be of any help either. When asking about the RS Corrected and RS Uncorrected with them today, they told me you want both to be 0 and anything that shows up in RS Uncorrected is beyond the ability of the Tivo Roamio to fix. When I pressed for what could cause the unfixable errors I was told it "could be any number of things including bad coax." I appreciated them narrowing things down so much! |

Looking forward to your attenuator tests, with hopes of making your signals more acceptable to the Roamio. |
Is it correct to say that your antennas are on the west side of your roof? If so, does the C2V clear the peak of the roof when aimed NE?
From you photos, it looks like the 91XG is already higher than the peak of your roof, and it has a clear shot at Fox. If that is true, then I see no point in moving it. |
When you gave me the coordinates for your house, I assumed the teardrop indicator was not only was showing me the right house, but also the location of your antennas. It seems that my assumption was not correct.
I have sent a set of new coordinates to you by PM that are for the tvfool interactive maps feature, satellite view 45 degrees oblique. Please let me know if I have it right this time, or correct me. |

Also, I am going to begin to look at bringing out an electrician to ground it (assuming it isn't currently grounded). Is the only thing I need materials wise a single grounding block? I know I asked before, but I'm just trying to double check and think about what I might need to have on hand that an electrician might not have. |
I am not able to answer your quick questions. You have not given me enough information to give you good answers.
I don't live near you, so I can't drive over to your house. I can only go by what you tell and show us. The first thing you need to do is answer my latest PM with the title Location 2. If you didn't receive that PM, I will send it again. Then you need to answer a few more questions that I have. Then I will answer. If you are going to intentionally WITHHOLD the information that I need to give you GOOD answers, then my answers will be CRAPPY. GIGO I really want to help you, but you are making it difficult for me to do it. With respect and good intentions, rabbit |

OK, I will wait until later. That will give me time to help my wife.
I have been neglecting her to help you. |

Here are some new pics I took this evening. The side photos were taken on the right side of the home. The other pics were taken from the back of the home.
