4x8 multiswitch, or better yes, a WB6-8, or wait and see what the new G1 compatible LNBF needs.
In whatever case, you get 6 receivers for yourself, and take two to the cabin and back, for when you go there., Or get two more receivers to leave at the cabin and move your account there when you want satellite TV there. That would be legal under your TOS, HAFH, and what the channels want (service only at one service address at a time)
Your tenants will need to get their own receivers and subscription, to be legal, as far as accounts go, since they are yet another service address. To be even more legal, have them get their own dish.
