Hi: I'm a newbie here. We are presently in wintering in our RV. I've taken the 322 recvr from home, along with a, (freebie), Dish 500 Sat. dish. The lnb is a dual Dish Pro, with 119 & 110 labeled on housing, having only one cable output per lnb. I have a basic question. Can I hook this directly to my recvr with one cable, or do I need two cables, or is it more involved then that? Any help appreciated. (the 322 has dual tuners).
