Pole Mounting a 1.5 M dish above the roof line

Navalcarnero

Hi,

Now this probably sounds like madness, but there are reasons. I have recently move to outside Madrid and i basiclly need a minimum of a 1.5M dish to get reasonble reception out here. The second issue is where i am i will need to pole mount the dish and its a big one. I am not sure of the exact make, but i am informed these are just about as good as Andrews but about half the price. They are simialr construction so fibreglassrenforced epoxy, 20 kg. So it a big damn heavy dish and i want to stick in on a pole. On yeah and i live half way up a hill with a gentle sloped valley below me which cant be great for winds.

Is this at all do-able? This house is brand new so the brick work should be pretty good, and i was thinking of building all the bracket work myself. A mate here has a welder and i have got a reasonble amount of experience with arc stuff from growing around farms, back in Glos.

I was thinking of building a setup using the biggest diametre pole i can get 3.5" i think going through the dish mount and then then welding 3 standoff poles onto the main pole and building large plates with say 6 bolt on each to mount to the wall. So a total of 18 bolts.

The dealer (antnetdigital ) has one of the same dishes on a simple wall bracket, very heavily made though, using just 4 bolts. This though is in an industrial comples and their dish is very well sheltered from wind.

Also if all this is doable should i leave it at that or could i stick an polar mount and actuator on it?

I fully realise this is a tough project but with heavy enough mount with enough bolt would it be safe? I really dont want a 20 kg ufos flying into Jose or Pedro garden, cos

a) It cost a lot and its mine
&
b) cos i seems rude to kill ones neighbours when you have barely got to know them

Any advice very greatfully recieved,

Phil

Stick it on a pole in the ground if you can. Consider the elevation you need, does it really need to go on a wall?

Missus doesnt want it in the garden or on the wall, in fact she doesnt want it at all but still. To be honest the garden is quite small and that a big dish so i would prefer to get it somewhere out of the way myself

Any chance of a picture with say an arrow South.

What we'd check first is if the brick work is not that hollow stuff* and the structure of the house where it is going - you're right to be concerned, a big dish badly fitted could damage say a gable end wall theoretically causing a crack or worse.

Consider putting steelwork on the inside if it's in a loft space and won't be seen, strengthening the wall to roof structure and also reducing the visible steelwork on the outside for the missus.

We've done gable end installs right on the apex in very exposed locations and put steelwork through to the inside of the roof so the building becomes far stronger on the corner where the dish is. House walls are built to hold the weight of a heavy roof but there isn't that much strength laterally- it's not needed.

With a dish that big I definitely agree that if you could it would be best ground mounted.

Thanks so much for all the advice,

To be honest i am going to work on the missus again about tryign to stick it on a pole in the garden. Just seems safer, one issue as that are garden is surronded on all fours side by 2 meter high chicken wire ype stuff which i am a bit worried about, not sure how far awya from it can get.

I might in the future try and stick it on the roof. Our house liek a lot of spanish places is basiclly built as a cast conctrete shell, with bricks used to fill in the gaps. These are partially hollow though not the type of clay pots they use to build partian walls.

The weird thing about our place is the roof, this is odd in that it looks like a normal pitched tiled roof but is actually a solid 12inch thick peice of solid concrete, cast in place, which then had a inch of insulation sprayed on top and then tiled over. There is no roof cavity space. The roof extends past the house at the back to create a large shaded area with large pillars supporting the end of the roof. I think given the huge strength of this area and the fact i can bolt directly to this large concrete slab in the future it would seem like an ok place to stick it.
