I assume the cabin has power, otherwise you couldn't plug the TV and
frontend in? (OK I know therwe are alternatives, like
batteries/solar), but depending on how the wiring is done, could you
possibly run powerline on the exiting wiring. EG if the cabin is fed
it's power from a sub-feed from the house?
