I am looking for a little help. I have Direct TV installed in my house and I want to set up a TV in my barn. I bought a used Direct TV 18" dual LNB dish at a garage sale and want to install it on my pole barn (it's about 200 feet to the building from my house. I have D11 receivers and I want to take one from the house and put it in the barn. Do I need to run in two coaxes from the dish? If so do I need a multi switch if I am only going to have only one TV out there?
