Quite true but the back of my house is fairly exposed and the missus would freak if I put up a mount on the back wall like yours.:)
I wouldnt sleep well with it on the wall.

I am going to ground mount it at the bottom of the garden in between some trees where it will be nicely sheltered and not an eyesore.
I'll run the cables under the lawn for 20 yards through alkathene piping .
Its not an ideal solution but the best I can think of due to the layout of the garden .

Lol.
I am actually surprised because when she saw the T90 she didnt seem to mind ,I was fearing the worst.
I had a 1m motorised dish before and I think she got used to it ,in fact dare I say liked it .:)

I understand what you mean, I'm lucky as my wife watches only Sat TV namely the Arab channels, the TD 110 facing Arabsat and the CM 120 facing Nilesat are for her, the T 90 is for us and the kiddies.

The sat pole is bolted to the wall which is concrete on the otherside of the wall with threaded bar used to to secure the pole. I sleep well at night and would be very surprised to see any problems.

The way things are setup we don't see the tri dish config unless we want to. The neighbours who see it couldn't give a monkey as they are just passing through and spend most of their life indoors.

Can anyone give me an idea of how big a hole I'd need to dig for the 60mm scaffold pole which is about 7 feet long.
What is the best way to secure the pole ?
I was thinking of putting rocks around it to hold it in place ,get it plumb ,then pour in cement ?

You need steel too, not only cement. It stops the cement cracking or something.

The size of the hole does depend on how wet the ground is, the composition of the ground (amount of rocks etc). it would also be a good idea to stop a few inches before the top, so you can cover it with topsoil and grass.

As for the cement you need a "strong mix" as opposed to a normal cement mixture.

If it's only for a t90 mounted right on the grass then it does not need to be big at all. I would say 2ft x 2ft x 2ft. It needs to "lock" into the ground so if the ground is not hard you may need to go deeper. Consider also how the cables will run to the dish. It might be worth putting in a pipe for them.

Better go for overkill rather than have it fail. Also consider you might want to put a different dish on it one day. Check for sewer mains, water mains, gas, power to the shed in the garden etc before digging

All good advice from zg above. I wouldn't bother withe the steel however. Handmix Gravel, sand & cement ( any builders providers ) 4:2:1 with water (forming a concrete mix ) and pour into the hole, ensuring the pole is plumb supported. Allow to set. Job done.

I have cemented pole deeper than 1 meter, used more than 100 kg of concrete and stones.

Rima, your work, as always, is class. Must have cost a few € for the metalwork

Excellent info zg3409 just what I was looking for.
The link you included is very good too.

Sounds like a plan .;)

I have started the hole ,its at the bottom of the garden,mostly just soil and tree roots .
Its near the septic tank but there are no pipes near where the dish will be so ok to dig.

I tried to get the dish bracket to sit on the 60mm pole but it wouldnt go on fully,the pole is too bloody wide ,I'll have to smoothen it down .
Was a struggle to get it back off it .:(

It could cost a lot if I did not have a friend-metalworker.

At long last I am going to move my T90 from its temporary position in the garden to the back ,south facing ,wall of the house.
The plan to locate it at the bottom of the garden hit a snag when I found a septic pipe when digging and had to abandon ship.:(

I have two options ,either use the standard T90 mount or use a TK bracket and have the 6 ft pole rest on the concrete footpath to take the load of the dish.
I get ferocious winds blowing up the valley towards my back so I want to have a sturdy setup.

I think the TK brackets or a H bracket is the best option .

I have been looking at 12" TK brackets but I think they may be too short .
My house faces due south and I would be centering on 13e ,so the dish would be turned ~20 degrees toward the house.
I want to do as neat a job as possible but dont want to sell myself short.

I was thinking of using rawlpugs like these
http://www.tvtrade.ie/shield-anchor-projecting-bolt-m8x25mm.html or Thunderbolts like this http://www.tvtrade.ie/thunderbolt-m8x60-1s.html
The wall I am drilling is dashed so I wont know which is solid block and which is mortar.

Anyone have any recommendations or feedback ?
Thanks
