Chicago Dish 1000.2 or 1000.4

[theedudenator]

I am looking at Satellite Finder / Dish Pointing Calculator with Google Maps | DishPointer.com

If I select 1000.4 my line of site is blocked by various trees.
If I select 1000.2 my line of site is clear.

Is there any reason why I cannot use a 1000.2 in the Chicago area?
I want to go from a 500 dish to a dish that can accept HD content.

I would say you would be perfect with the 1000.2

Chicago is on both arcs. According to a post Scott made a month ago

Chicago new installs are western arc. So you should be OK with a D1000.2
