advice on possible new install

[hammy]

hi guys
please accept my apologies if my queries have been covered before but i have spent hours trawling this extremely helpful forum and have gained a lot of knowledge prior to taking the plunge.

i would love to open up the world of the satellites to make the most of my recently purchased , supposedly perfectly capable, reciever (cuberevo mini).

i have narrowed my questions down and would appreciate any specific advice.

firstly my options are limited on size & positioning of the dish & i intend to have a go at it myself.

i would like to go with a motorized set-up to realisticly get about a half a dozen or so satellites.

my dish would need to go on a wall in a back yard at high level (about 4.5 metres), to look over a roof . i am quite caplable on ladders.

the maximum size i would be happy with regarding looks, handling & setting up on a ladder is 80 cm.

i have seen full kits available which look quite capable for around £100

q.1 what would be the limitations of 80cm from 30 deg west to 30deg east which is roughly my clear view of the arc. my location is belfast n.ireland (latt 54deg).

q.2 i would like to make the dish mount as unobtrusive as possible so would a 12" standoff wall mount bracket + the motor (tm2200) be sufficient distance from the wall for an 80 cm dish to turn 30 - 30 deg given that the wall it is being mounted on is roughly perpendicular to 7 deg east of due south (according to dishpointer).

sorry for the long-winded first post.

thanks
ham

Hi,


One limitation you may have is receiving from 16E, 80cm may be too small for a reliable signal in your area. There may be others, like 1W and some 23E but not sure.


I think I understand the details of your mounting position, but could you post a screen capture of dishpointer, to make sure.

If the dish looks straight over the roof when pointing due south roughly, the length of the brackets depends on how high above the roof you put it and the slope of the roof, and the length of the LNB arm. The easiest way to check would be to get up there and have a measure up. I would avoid the 24 inch T&Ks if possible as they wobble a bit unless strengthened. Low down, its not a problem, but exposed like that, it could be.

hi robbo
thanks for the reply.
here is some more info.
i have included a couple of photos to help explain if what i am looking is going to be feasible.

photo 1 shows the back of my house.
i was hoping to be able to install an 80cm dish in the position marked with the 'x'.

if you intersect that wall with a line at 90 deg then that line is roughly 7 deg east of due south.

i was hoping to get from 28 deg east to about 30 deg west.

photo 2 shows the position of the back of my house in relation to a nieghbours sky dish. it is on a wall opposite were photo 1 shows

now you can probably see why i would want a shorter wall bracket as to keep the dish as far away from the obstruction of the right hand wall and roof as possible in order to see over it.

i could go down the road of mounting a pole on the right hand wall but this would mean working at the dish up over the top of the roof and would rule me out as a diy install which would add £££'s to the cost to have a professional install the dish.

i could probably go to a 90cm dish max, hopefully this would improve the chances of a reliable sig from 1deg west.

let me know what you think and thanks again for the input.
cheers

p.s. date & time on photos are wrong, taken today.

The dishpointer picture would have been useful still. Words can be ambiguous.

So, say for example a minidish was mounted on that wall with the cross for 28E, it would face to the right, looking at the wall opposite?

Difficult to tell from the photo because it has been taken from low down, but it looks to me that the dish will have to go above the roof anyway. You need to check the angle. Since the roof overhang is very short, 12 inch T&Ks would be long enough.

Putting a dish above the roof is not as difficult as it sounds, I have done a few like that. I usually use two sets of T&Ks and have 5 foot below the roof and 3 foot above and a long ladder, anchored to the wall, with a ladder standoff.

hi again sorry for the delay in replying.
i have taken a couple more photos.
you can see the neighbouring sky dishes in the background which i presume are looking at 28deg east.
i was hoping to put my dish in the position marked with the circle to make it more discreet than pole mounted over the roof opposite.
i am unsure if the opposite wall/ roof is far enough away for the dish to see over it from the position i have marked?
you may not be able to say either way just by looking at all the photos but it is worth a try.

Yes, I still think that that position is a no go. The angle to the top of the roof looks too high. If you want to make sure then make your own inclinometer using a protractor and a piece of string and a small weight , or get one of these:- ( I never leave home without one)
