I don't think it would be useful for most amateur radio which doesn't need the gain and balloon would be huge. It would be useful for people who do higher frequencies and use satellite dishes. Portable link to 2.4GHz mesh network would be example. It might also be useful for cheaply making big dishes for Moon bounce.
