I take one or two receivers to my cabin for 1-3 days at a time. In my case, I have one antenna on 110/119 and another on 129 at both the house and cabin. On the DPP44 switches, I make sure I have 110, 119, 129 on switch input 1, 2 and 3, respectively. Since my cabin is only 75 miles north, the receivers (622 or 722) don't even recognize they've been moved and I never do a switch test. I've noticed that 129 is not as strong at the cabin, and in bad weather I get more signal drops at the cabin. Just don't call for support while you're at your cabin as Dish sees the number you're calling from is not the number the receiver is supposed to be at.
I just had Xfinity come to my house yesterday. I told them that as long as I could use Dish at both houses I'd stay with Dish. If Dish ever bothers me about me taking the receiver to my cabin this "Hey, I see you're one of our best customers" will be an ex-customer.
