Any metal in front of the DISH will kill all signal to it. You will have to find another location for your dish. The hole is in the wrong place and isn't going to work unless it is in the perfect place.satzilla said:
Patio roof interference
Hello, how bad is a patio roof made of aluminium bad for reception?..I lost all signal when I installed a brand new roof over my sat dish (dish network 500)... The roof crearly interfered with the lnb's so I moved it to a new position but still under the patio roof but with an opening of about 20 by 15 which I though would be enough to get the signal back and yet the signal still missing...so I was wondering if the roof itself is acting a a general shield for my reception?
TIA.
TIA.

You'd probably have to put the entire dish through the opening to have it on top of the roof to get it to work. Using a 84101 zipcode, the receiver shows a 163° Azimuth for the 110 sat and 177° for the 119 sat. The elevation of the two is very close there - 42° and 43°. So it is trying to get signal from two places that are 14° different Az. It can do that if the dish pan is right in the opening, but that puts the LNB on top of the roof. The farther you drop the dish pan from that 20x15 opening (if that is feet and not inches, it should work now), the less likely you will still be able to see both locations. What you described "sounds" like you think the signal is coming down from where the LNB arm is pointed. It is actually getting 110 from 7° to one side of the arm and getting 119 from 7° to the other side of the arm. To see both "from the floor" that is 8' from the aluminum roof, the opening needs to be about 27" wide. Even that is just so that each half of the dish sees "its own" birds. You really need both birds to hit most of the surface area of the dish. Are you mounting this on a pole so it is as close as you can get to this opening in the roof? About ever foot you come down from the roof means the dish needs to be moved a foot away from the opening (if it were a 45° elevation instead of 42.5°).
I'd extend the receiver coax outside the patio area - say on top of a picnic table where you get a good signal. Then take a piece of metal with a 20x15 hole in it and see where you can put the metal that doesn't knock out the signal. Or just leave the dish mounted outside the patio! It would be far easier than what you are attempting. I'm with whatchel1 - I don't think you'll find the "perfect place".

You can see here how much clearance it has on front of it. I did drop the dish about 3 ft. (Originally sat right under the soffit for 10 years without any problems) and also moved it about 20 ft east from where it was originally located. I do like this new location because it shelters it from the weather but I guess gonna have to take out of this location too.

The lighting is bad, so it's hard to see the dish itself, but even with that, I can tell you there's no way you're going to get signal with it mounted there. It's going to have to go above the roof.satzilla said:You can see here how much clearance it has on front of it. I did drop the dish about 3 ft.

The thing is, you can say "well, the line of sight out the dish is exactly right" but it's not. The LNBs are offset, and the actual line of sight is not along the axis of the dish... the actual angle is WAY higher than it would appear just looking at the dish.
Go ahead and move it out from under the new roof. You're never going to get it to work there, and moving it around under there is only going to waste your time.
I'm trying really hard not to be snarky ... you do need a clear line of sight. Anything between the dish and the sky affects signal reception.satzilla said:You can see here how much clearance it has on front of it. I did drop the dish about 3 ft.

The "elevation" given on your point dish screen or manuals is accurate for looking straight at the satellite. Get a protractor and a level and stand or sit where you want to put the dish. If the line of sight clears everything you should be fine.
My dishes are low mounted on the side of my house under an eve and I agree that the position is nice to keep weather away ... you just need to see around the roof.
