Nat;
All the world looks likes nails, when you're a hammer.
Battery operated satellite receivers would seem to be a work-around, or
those mobile sat receivers in Escalades come to mind.
Yes, a Hurricane in New Orleans means that it's difficult for you in
Maryland to watch local TV stations from the scene.
People in trouble want long-lasting radio batteries. TV batteries last
minutes of use; radio batteries last weeks.
You can watch the disaster on your TV. People in New Orleans aren't
complaining about no TV; they're complaning about radio batteries, and cell
phone service (among communications needs.)
