General Dish setup question. I have two VIP211k's on my Dish setup. I have two coax cables coming from the LNBF, one coax goes to the first VIP211k, the second coax goes to the 2nd VIP211k. So in essence, the VIP211k's are directly connected to the LNBF. There are no switches or splitters or anything along the way. Does the VIP211k receivers send power back through the coax to power-up the LNBF? Basically power over coax?
