I don’t think that the explanation is entirely correct. Inflating a balloon will produce a spherical antenna not a parabolic one. Now I don’t really remember the implication of using a spherical receiver for radio waves, but in case of light waves it’s necessary to use a parabolic reflector instead of a spherical one to avoid spherical aberration.

In this case, the spherical shape is an advantage. See uoaei's post (above); https://news.ycombinator.com/item?id=38043955#38045556 https://news.ycombinator.com/item?id=38043955#38045556
