Mounting a motorised dish on a flat roof

Thanks for wrapping that up nicely!

The holes in the mounting brackets are elongated so they can slide left to right. The same is true of the holes where the mast is attached allowing adjustment in both vertical planes.

Which satellite is your minidish pointing at in the picture above?

It seems to me that if it is pointing at 28.2 East unless your motorised dish on the flank wall or on the Garage roof, you won't get 1 West or any further West.

**erukus** · 26-05-2009

Yes you are right this is a really silly error by me but I thought I had a flat roof at the outset of this thread until I went out and observed it more closely OOPS sorry that was really dumb It is a rented accomodation I am hoping to put it on the wall now I have marked the picture with an X if you have a look can you tell me if this is an appropriate position to recieve 1W and the other satellites

***compufunk*** · 26-05-2009

If you can get away with it, id mount it on the wall facing left, (Where the chair is).

**Robbo** · 26-05-2009

Yes, the south facing wall would be ideal.

On the wall with the cross, you wouldn't get much past 1W as the dish would hit the bracket, and be blocked by the wall.

**sonnetpete** · 26-05-2009

How about going up to 18" or 24" T&K's and mounting the dish as far towards the corner of the wall as possible? That way the rim of the dish would 'peek' round the corner.

Alternately, you could mount it between the top and bottom mounts of that aerial on your south wall, if no-one objected and the mast was really plumb vertical.

By the way, you're going to have a difficult job painting out that red cross on the wall, seems a lot of trouble to go to just to mark up a dish site

There are easier fixing positions like the far wall as said, but you can still mount the TK on the spot marked "X" if you wish. Should see a reasonable amount of the West satellites but the dish will been very exposed and visible.

Really,

Thanks for telling me that -- thats pretty important. At position 1 in the photo I am attaching with this post this would be the easiest for me to install. Position 2 would be extra complicated. Would position 1 be sufficent or would the wall with the sky dish get in the way? Thanks v much!!

**Robbo** · 26-05-2009

Position 1 would be fine, the wall is too far round to get in the way I think.

Position 2 looks to have access problems.

It does of course depend on the view of the arc you have at each point as well though.

Pos 1 would be the easiest option. To add to my earlier post re: mounting on the spot marked X, to see over the West the dish would need to be mounted on a TK and above the roof line.

**erukus** · 26-05-2009

Position 1 it is then! So is anywhere in that area ok then? should I try to keep it to as close to the end as possible? Satelliteman can you confirm that the wall with the sky dish will not interfere! If you could mark on the photo exactly where I should put it that would be great. I would really appreciate it.

Thanks

**satelliteman** · 26-05-2009

Without a correct site survey, it's only approx.

**Robbo** · 26-05-2009

Judging from the angle of the minidish, the position 1 wall faces south. Judging from the position of the other wall, it would not get in the way,as you'd be below the horizon before you got that far.

**erukus** · 27-05-2009

Ok I have added some more pics that I have taken from inside the upstairs bathroom to see the view from where the satellite dish will be. I am doing this as I need to be sure as my landlord is ok with four holes only so i get one chance only.

Here is what the numbered point correspond to 1 the window i took the pics from 2 the bottom of the aerial from outside 2A the bottom of aerial from inside 3 proposed location for dish 4 bottom of second aerial from outside 4A bottom of second aerial from inside.

So the question is will th neighbours house or anything else you experts can spot block the signal from ths position or will I be okay?

Thanks

here's the last one

Position 1 looks pretty good.
I concur with Robbo that it looks south facing (almost perfectly so).
With a good T&K mount, you should be able to see 45W no problem, and as far as I can tell from the pictures, as much east as you'd like to go?
It's difficult to tell from the pictures, but I'd also suggest that you don't need to put the mount right at the top of the wall. You only need to mount it high enough to see the arc.
If you could take a couple of pictures with your back to the wall below position 1, maybe we could offer some opinions.

Edit to add:
Looking at the pictures again, it appears you have got some trees to the east. Might be better to get it up as high as possible if you want to go beyond 45E?

It will only be guess work without a correct survey being carried out. Snap shots don't show the whole picture and no guarantees can be given of the range of the arc.

Do you reckon he'd notice an extra hole?

as with the T&Ks you'd need at least 5.Two at for the top and at least 3 for the bottom(though I normally put 4 in).

**erukus** · 27-05-2009

LOL ya I think he will be okay with 5 ha

Should I stand on a step ladder with my back to the wall at the propsed dish location and take more photos? or have ye seen enough? are any more photos going to make a more accurate guesstimation?

**satelliteman** · 27-05-2009

From the look of it, 1W will be bang on 90 degs out parallel from the wall. Should nail a good range of the arc

I think the only problem you would have, would be if you want to look beyond 45E. My guesstimation, from your pics, is you will be fine from the top of a step ladder, with the added bonus, that it will make your install easier.
If you are happy to install from the top of a ladder go for it, but it will mean tweaking your dish is going to be a bigger problem.

One tip, if I might offer it, is make absolutely, positively, certain your mount is perfectly plumb !

Get that right, and you will save yourself a load of headaches!

**sonnetpete** · 27-05-2009

Yep, absolutely, positively make sure that mount is plumb. It will save you no end of headaches, not to mention trips up and down that ladder!!

Don't think you have much to worry about re the arc, I have quite tall trees within 30 metres of the dish and still manage 45E. My dish is only mounted about 3 metres from the ground.

**erukus** · 28-05-2009

Can someone tell me what is the recommended vertical spacing between the T&K brackets if have seen somewhere in a thread it should be a minimum of 600mm! Also what length of pole should I get? And finally I was wondering if there are any issues with going too high and the eve shoots. I have ordered 18'' brackets!

Thanks
