I like to recommend a temporary coax for initial setup. Otherwise, you're at the mercy of whatever is installed in the satellite coax system and we get calls about that every day that go like :

Caller: "Hey, I swapped my dish for your antenna and nothing works. What's wrong with your antenna?"

Answer is "Nothing, you didn't remove the satellite-specific hardware that blocks TV signals". [Sugar-coated, of course]

Multi-switches are the usual culprits.

Pre-amplifiers, if used, are remote powered and do not require AC power in the near vicinity (see installation instructions). I'd suggest no amp to start out with. If you elect to use one, pick one that tolerates strong signals.
