I'd recommend installing a permanent full sized dish at your residence to use when you're there. The portable domes are good for RV use, but they are more susceptible to rain fade than the full sized dishes. Also be aware that the dome dishes will only get SD signals on DirecTV, and only work with a limited number of Dish receivers, although they do get full HD service on Dish.
We're currently in Florida and rode out the storms that hit all over the south the other night. Our total Dish signal loss time was less then 10 minutes spread over the entire several hour event. On the other hand, one of our daughters in upstate NY lost her cable TV/Internet service in a snow/ice storm yesterday, and it's not back on yet. There's something on TV tonight she really wants to see, so she's going over to our cottage to watch it. On satellite... :)
