Dish Siting Problem

[finality]

Hi,

Looking for some confirmation (putdowns) on the solution to my dish mgt problem.

System coming = 80CM motorised with tm600

Problem

Covenants on property stop all but east siting of dish.

Only east wall available
[IMG][/IMG]

Cannot cross front building line or use roof.

So

T &K + Scaffold pole shaped as 6Ft Supercrank or normal crank



Length is open to adjustment but what it will do is
tounge in cheek "mount on East Wall" slacken crank to T&K
Swing Crank south 300mm or so which from cad dwgs gives me arc from east to west of 96%

Addition buckle cable to scaffold allows for adj to vertical.

Seems to beat all covenants and allow me arc req for motor sys.

64,000 dollar Q

Will it work and support weight of dish/motor 8kg?

any comments appreciated.

how about a scaffold pole at the bottom of your back garden there seems to be room from your pic.

Hi,

Thanks for the suggestion, i'm not sure (do not know) how steep the line of sight (inclination?) would be needed.

I'm guessing that for instance a site that gives figure from
X east to Y west exists as I only have roughly 26Ft (7.8M) from rear house wall to fence at rear.

Be ideal if I could, but depending on hight req would have to keep away from fence for occasional local weekend night crawler trouble.

West side front of Shed(10*8* with pwr lght and pc), East side - side border.

Tool to measure other than mark of home made incline gauge?

Terminology prob wrong but hope you get Idea, and I will look for info on how to achieve incline east to west.

If you know of site / quick cheap way to measure would appreciate it as much easier for me to install at that level.

Cheers

you"ve lost me a bit with the jargon but the dish needs to be roughly twice the distance away from the height of any obstacle ie; 20ft high building dish at ground level needs to be 40ft away.if dish is 10ft up only needs to be 20ft away.I would suggest you do a temporary setup to see what you can get away with before concreting a pole in the ground (pole should have a third of of its height buried)

Thank you for the hight formula you gave me it is coming in very handy.

My apologies for the jargon I don't know the correct terminology but am slowly learning.

etc to west limit

Coupled with your formula my garden would need a blackpool tower with the Elevation and Mag/Az angle for a lot of them.

I think back to the gap at east wall with as you say temp scaffold pole ground up with scaffold clamps tripod will see what swing I get, at least I know the Elevation to start with centre and ends and inclinometer gives me figures without using receiver.

Thank you for you suggestions, it made me think a different way. Just hope it works.

Cheers

I hope you get sorted ok mate I must confess I usually just setup by eye with the help of a cheap sat beeper,the only thing I"m really careful with is to get the pole 100% plumb this is vital for a motorised setup but not so critical with a fixed dish.

There not many quality channels in the west mate.I just resited mine for an eastern wall down to bottom of garden and to tell the truth it was a waste of time.The best positions are in the east.

Satmandu is right mate ~ most of the good satellites are in the east ~ from 1 west (roughly due south & zero on motor and 26 degrees elevation) through to 28.2 east (roughly 35 degrees east on the motor and 20 degrees elevation in central Scotland).
If you pm your latitude & longitude I will give exact figures for these satellites.

Sorry for the delay on the thread but disaster on wed last

3 boxes by City Link (my prev exp = rubbish)

Box 1 = dish (hit by Edin - Kings X Express)
Box 2 = rec (resealed badly)
Box 3 = rattling

Peeked in rec (was brand new tm-600 what a mess)

Driver wanted sig, not from me, so he went off shouting and swearing.

checked supplier, many apologies new one to follow or if I wait discount on 800.

@Dick B

Funny just seen meter in screwfix ?13 (local) and across road beaver84 scaffold supplier new length straight as a die.
So I believe I'll get the meter as you suggest.
Thanks for the help.

@SATMANDU

And I've just talked her into above the gutter scaffold + 3 brkts (epoxied).
If I change again she will string me up
I think that from you and others I'm not going to get much on west, but I've got the swing now so I might as well let it travel.
Cheers.

@hypersonic
I'd appreciate it, PM on its way



Deal offered on the 800 seems to be good so I'll wait a short while, no longer, to get the better spec.

Helpful place to find, read and get advice from
Many thanks.
