Assuming a power supply, I was going to say "yes" to your question until I remembered one thing. My mother in the Bay Area has Dish, and I don't know if DirectTV is any different, but her satellite receiver box needs to be able to dial out on a regular telephone line periodically. I assume it's mostly a way for the box to check if you've been paying your monthly fees. Anyway, without a working landline connection, she won't get satellite TV. I know, bummer, right?

It's too bad that we never have true competition between multiple cable providers in the same area (at least, I don't remember ever living anywhere where I had that choice.).

Besides broadcast TV, one other option that hasn't been mentioned is TV service from the traditional telephone providers, like AT&T's U-verse service or Verizon's TV service that is available with their fiber optic FiOS service. But that is still being rolled out in many areas, so these services may not even be available where you are.
