A satellite dish would probably be very good yeah, as long as it's a reasonable size one
You'll need to remove the current antenna mounted though, as it's setup for a different wireless frequency.
The wofki dishes are quite directional. If it's a long distance (longer than my 1.2KM test), you'll probably want to use a compass...though if are happy to play with the mounting, you can just run net stumbler and move the dish around until you find the best signal quality.
