Our body is able to improve radio reception by touching an antenna. Could it also be able receive or transmit signals all by itself?

Question

… and if it’s possible to use the body as a transmitter, how powerful of a transmitter could a human be until health would be in serious danger?

Answer 1

Antennas essentially produce radio waves by jiggling electricity back and forth in a way that produces a wave in the electromagnetic field, which is your radio signal – just like a splash produces a wave in a pond.

In order to transmit structured radio (i.e an actual signal rather than random noise) you would need something to produce that jiggling of electricity – doing that uniformly would get dangerous to your health rather fast since it’d mess with the electrical processes in your body (like nerve signals). A biological organ to transmit radio would be theoretically possible – but we don’t have one, so we’d need an external power source to do so.
