http://forum.tvfool.com/attachment.p...1&d=1416634091 Just got another idea: What would happen if you used the 5 ft mast section that you just bought to raise the C2V 5 ft higher on the satellite mount? No "ugly" tripod needed, but if it doesn't fit it wouldn't work. |
My wife is wanting to know how much higher the mast would be sticking up above the roof if we go with the eaves mount. I wasn't sure so I thought I'd ask.

Short answer is "As high as it takes".
We are not able to stand on your rooftop and see what the precise distances and heights might be. The antenna will work best when it gets a clear and unobstructed view in the direction the signals are coming from. |

The eave mount itself at the back of the higher roof on the west side will not show from the street. Only the C2V antenna and the upper part of the mast will show. Quote:
You don't have a signal clearence problem, as far as I can tell, with the eave mount on the back of the higher roof where the eave mount would be fastened. That point has an unobstructed view to the NE, which is why that would be the best location for the C2V. If you mounted the C2V on a mast on the rear deck, then nothing would show from the street, and the reception at that location might be satisfactory, because it looks like that is also an unobstructed place. The antenna on the deck would become a conversation piece for "bragging rights" about free high quality TV pictures and no cable bill. The 91XG for Fox is doing well on the garage roof, as proved by your attenuator test to measure the "fade margin." After studying the photos of your house, it looks like the 91XG is also about as high as the top of the upper floor windows at the back, so even if it were moved up to a slightly higher location, the improvement wouldn't be much, if any. That is why we said leave it where it is on the garage roof. This might be of interest to you since you have a CM DVR+: New Firmware update for DVR+ #114R http://www.digitalhome.ca/forum/show...&postcount=826 |
Higher than what? If you mean higher than the roof itself, it would be something like the attachment. If you mean higher than its present location on the garage roof, then the C2V on the garage roof is about as high as the top part of the windows of the 2nd floor at the back of the house.
The eave mount itself at the back of the higher roof on the west side will not show from the street. Only the C2V antenna and the upper part of the mast will show. Yes she meant higher than the roof itself. If you mounted the C2V on a mast on the rear deck, then nothing would show from the street, and the reception at that location might be satisfactory, because it looks like that is also an unobstructed place. The antenna on the deck would become a conversation piece for "bragging rights" about free high quality TV pictures and no cable bill. Are you talking about using the 5 or 10 foot mast? I'm not quite sure how that would be mounted on the deck (and also figured other houses or objects would prevent the C2V from having an unobstructed view from there). This might be of interest to you since you have a CM DVR+: New Firmware update for DVR+ #114R http://www.digitalhome.ca/forum/show...&postcount=826 I had seen that over at AVS and thought about connecting via Ethernet to get the update. I haven't yet. One of the primary reasons I switched to the Tivo is because of a whole home setup which Channel Master doesn't have right now (but keep saying in January they are going to reveal something). The Tivo route for a DVR setup also seems to simplify my antenna setup a bit as I am only sending signals to 1 TV. I think it would start to get complicated to send signals to 3 TV's which each had a DVR+ connected to them (accounting for 6 tuners to drive). I would probably have to add an amp somewhere if I did that don't you think? |

The 10 ft mast is needed there for the greater height for the signals and so that the antenna would be above the head of anyone on the deck for safety. Quote:
http://forum.tvfool.com/attachment.p...1&d=1416714333 In the photo above Kevin is using a WG 7697P. If you want to read more about his tree problem: http://www.avsforum.com/forum/25-hdt...l#post17280909 http://www.avsforum.com/forum/25-hdt...l#post17283385 http://www.avsforum.com/forum/25-hdt...l#post17297708 It is true that the eave mount gives you the highest point. If the C2V there works well, your problem is solved. If the C2V works well only for the UHF signals, but there is still a problem with 10.1, then you will need to put a UHF/VHF-hi combo antenna, like the Winegard HD7694P, there. If your test there doesn't work because of obstructions, then your only alternatives would be a tripod on the upper roof or a tower in the back yard. Both of them would be difficult to do. If you then reach the point where you have no more options to improve the signals from the NE for the Roamio, then you are left with Plan B. That plan would be to demote the Roamio to a secondary role for recording only. The antenna coax downlead from the AC7 would be connected to a 4-way splitter that would feed the three TV tuners and the Roamio. Quote:
Have to leave now; more later. |
An update: My spouse is still very reluctant/hesitant to try the eaves mount. To me, it seems the option to have the best chance of success. Since she is still reluctant at this point, I feel I should explore other options that don't involve moving the C2V in any way first. To that end, I mentioned I had another DVR in my possession, the DVR+ from Channel Master, so I have tried it in the same setup to see how it would do (since every tuner can be different). The only change was the addition of the Holland Splitter (in this setup I don't need the Moca connection and need signals going to all 3 of my television sets).
91XG>Winegard LNA>Tinlee AC7 combiner>Holland 3 way splitter C2V> Tinlee AC7 combiner>Holland 3 way splitter Initial results hadn't shown any trouble with 33-1 (or any of its subchannels) or 10-1. What was noticeably different was the signal strength on 49-1 (Fox) was in the fifties and could fluctuate down to 48 or so (where some pixelation/cutout would occur). That seemed to suggest to me that the signal I was sending to the Tivo Roamio was receiving some sort of amplification once it got to the unit. In order to try and bump the signal back up (to eliminate the cutouts) for Fox 49-1 I made the following change (daisy chaining two amps): 91XG>Winegard LNA>Channel Master 3410> Tinlee AC7 combiner>Holland 3 way splitter C2V> Tinlee AC7 combiner>Holland 3 way splitter This caused 3-1 (and its subchannels to drop out). Because of the dropoff, I decided to add 6db worth of attenuation to the Fox signal to attempt to alleviate the overload. So, after that change the setup looked like this: 91XG>Winegard LNA>Channel Master 3410> 6db attenuator >Tinlee AC7 combiner>Holland 3 way splitter C2V> Tinlee AC7 combiner>Holland 3 way splitter I thought I had "fixed" the overload as for a while 3-1 and everything was back and in the 80's on the signal strength and 100% on the DVR+ signal quality meters. But, back came the pixelation/cutouts on the 3-1 (and its subchannels). I was able to confirm that the cutouts are not relegated to the DVR+ only. The sole regular television set I happened to check for the same issues on was doing the same thing. I am going to try to see what the 3-1 signal looks like when I take out the Channel Master 3410 and what it looks like leaving it if I up the attention to 9db or so. Other than that, does anyone have any suggestions regarding adding the little "boost" Fox seems to need when in use with the Channel Master DVR+? Again, please keep in mind these are alternatives I am considering that don't involve the moving of any antennas in order to exhaust all options to appease the wife (if all we are left with is that option). I appreciate anyone who chooses to provide feedback. |

Just posting an update: After a long wait to follow suggestions in this thread due primarily to an expensive unexpected car repair I was finally able to follow through yesterday.
I used this eaves mount: http://www.amazon.com/Winegard-SW-00...sin=B001DFTGUQ and got my Antennas Direct C2V mounted to it at the suggested location. Also got the antennas grounded using I believe 10 gauge copper and a dual grounding block. So far, so good. I would like to thank rabbit and ADTech for all the feedback, suggestions, and time spent assisting me on this thread. I felt it important to update because I wanted those two users especially to know how much I valued their time and effort in assisting me. Plus, I wanted them to know that I did follow through with the suggestions given even though quite a bit of time passed from the suggestions to the follow through and execution of the suggestions. |
