It is possible to mount the skytv satellite dish to a ground pole similar to what you see in these pictures:

Should the pole be metal or steel? And should heavy duty concrete be used?

I have been trying to find out whether a building consent is required in the Auckland city council region but I cannot find any info on this. Would the skytv installer take care of the building consent(if required) and provide the pole and concrete it or would I need to get a builder to take care of the consent, pole and the skytv installer to take care of the dish? 

I have no idea on how the cable would run from the pole to the house but I was reading that the cable needs to be grounded in case of a lightning strike.

The reason I don't what the satellite dish mounted to my house is because of the leak danger.

And when skytv installs a phone line socket does it have a dsl splitter installed or do they give you an external splitter?
