I use the Dish western arc on mine and if I want just only regular channels and my locals all i would use is the Dish 500 and sats 110 for locals and 119 for the rest. But I wanted HD channels so i now use my Dish HD and it use's 110 and 119 like before but then you use Sat 129 and its for the HD channels. Of course I only use the HD dish now.
Hope that helps
I still say spend a little for the HD dish or find one nobody wants and then use your receiver from the home and your all set for less than 100 dollars. My tripod set up is not that bad but yes I do like the auto ones but wanted to save money for the same outcome.
