I have a VIP722K in the house and a VIP612 in the shop. The 2 receivers are approx. 150' apart. With the shop receiver being in a metal outbuilding. I was thinking of upgrading the 722 in the house to Hopper with sling. I have internet out in the shop. Would I be able to use sling to watch tv out there? Would a joey reach that far? Same with another tv in the house I don't watch that much, could I just use sling to save the cost of a joey?
