I have a DishPro twin dish going into a DP34 switch. I'd like to add a dish for 148, (mostly for Classic Arts Showcase) but I don't want to buy a DishPro single LNBF. I have a spare DishPro Dish 500 LNBF. Would it be possible to set that up as the 148 location and connecting it into my DP34 switch?
