There are several application that can benefit
from a "levitated" antenna / transmitter setup.
Now, if we change the bird to a balloon, then many
applications come to mind. I guess the main thing
that I'm trying to picture is that how to go about
predicting a signal coverage. That is why I asked
about if it changes the radiation pattern.
This came to mind because from what I read many
antenna setups are limited by the laws governing
its area of installation. I don't think anyone wants
to see a 500ft mast on their backyard. Also, materials
would be expensive.
