Emphatically not. Every chunk of space, propagation direction, and polarization has its own spectrum. Draw a box, count the photons. If you point a satellite dish at different satellites, you see different signals, even if the frequencies are the same. The same trick works for "virtual antennas" built out of phased arrays of real antennas, except you can steer them in microseconds and without any motors. MIMO leverages this.
