I am scheduled to get a install of Voom on March 25th and was wondering what direction does Vooms dish point? I also have dish network and their dish points southwest here in Wisconsin. I have 3 trees due south of my house and am concerned about signal blockage. I do have a older 18" Direct tv Dish mounted on the peak of my roof that was used about 5 years ago. Will it be in the general same direction as the direst tv dish??
