I would seriously consider waiting until the wife is decided on staying put, all your good work may need to come down :)
But if you would like to put it up use Dishpointer, its a great online tool to help you with site survey and alignment. What size dish are you going to use, I have a 1.2mt dish but its at low level as I have a South Facing garden with lots of space and no obstructions.
I use T&K brackets with a scaffolding pole at the moment, works well and is very stable. But is also well sheltered, so a good site survey is the way to go ;)
Any nice Mod about to make the last few posts into a thread for Sat set up in Ireland please :)
