So many posts on this.
If you want to be 100% legit then get 2 accounts.
If you have an account at home and only go to your vacation home on the weekends, you could install a second dish at the cabin and take one of your receivers with you on the weekend.
It’s really not an issue if your doing this a few days out of the month.
If you want to leave one of your receivers at the vacation home, it’s a grey area and the providers usually look the other way If it’s really a vacation home.
If someone is living in the other home full time, you need a second account PERIOD!
