If they're not connected, then they're just two antennas. What happens when you get far away from your wifi hotspot or a cellphone tower? The voltage/energy transmitted becomes vanishingly small, and smaller than the thermal noise of the electrons in the other antenna, and undetectable. https://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise |
