Why not put the horn inside the balloon such that it will be in the correct position once inflated?

- mikewarot 3y agoIt's simpler on the outside, less holes to make in the envelope of the balloon.
- cwillu 3y agoEvery wire/tube/whatever you need to be inside the balloon is another place for a seal to fail. If the material of the balloon is transparent to the signal you're looking for (as it must be: the reflector is inside and the the universe you want to look at is outside), then there's no benefit to be had.
