re: Best way to acquire a Direct TV dish for a camp?

If you call DirectTV, do not tell them that you are installing on a permanent structure. They will charge you for a new account.

I recently did this exact same setup for my camp.

I called a local Satellite/Internet provider in the area; told them what I was doing. They have the parts and installed it for <200. Much easier than doing it myself and any snags, they deal with.
