Calgary Skew for Dish 500

[dss_dork]

I need to find skew angle for Calgary using a Dish 500. Does anyone out there know what it is or how I can calculate it???? Thanks for your help!

Found the answer to my question, just used zip code for a town straight south of me in Montana. Used Dish menu to calculate skew angle for me and tweaked after 119 Sat tuned in. As it turned out I didn't have to change skew at all, it seems 90 works for Calgary (and most of Northern Montana ). I also found out you have to move dish about 6 degrees east of where it is pointed if you use a regular dish pointed at 119 (this is for Calgary and area) and that the switch is to be installed after 119 is found and tuned in. Hope this helps someone else out there!!
