Ok. Tommypic provided the missing information.
LNB type: DishPro
Switch type: DP34
In order to duplicate the programming you receive at your main house to your lake house you would need the following.
Dish500 with a DishPro Twin LNB aimed @ 110/119
Dish300 with a DishPro Single LNB aimed @ 61.5
DP34 switch.
RG-6 cabling, etc.
If you don't need the programming at 61.5 (WNTV 29, WGGS 16 and international channels) you can get by with just the Dish500/DishPro Twin combination.
If you choose the second option you will need to run a Check Switch on your receiver each time you move it between houses.
