When an alternating current is sent up and down an antenna, an alternating magnetic field is created around the antenna in accordance with Ampère’s right hand grip rule.
When the current is going up the antenna, photons are sent off spinning one way. When the current is going down the antenna, photons are sent off spinning the other way.
The polarized photons rush off in all directions at the speed of light.
When some of these photons hit a receiving antenna at a distance, they induce electricity into it. The received signal matches the transmitted signal exactly. It can therefore be used to reproduce the transmitted message.
This is how radio transmission works.
It should be noted that this can only work if the photons crossing the space between the transmitter and the receiver carry some energy with them. This is because electrons have inertia. It takes energy together with spin to set them into motion.
Since zero-point photons carry no energy, we know that the photons used in radio transmission cannot be zero-point photons. Radio transmitters do not only set zero-point photons spinning, they pump their energy up too.
The energy required is very small. Radio-wave photons are the least energetic of all detectable photons. They are just one step up in energy from zero-point photons.
Note that while electric generators and motors work by creating strong magnetic fields to bridge the gaps between components, radio transmitters work by giving energy to polarized photons. The large distance between transmitter and receiver makes it necessary to send energy together with the photons involved.
The tiny gaps between stators and rotors in generators and motors are bridged by magnetic fields. No added energy is required for this to work since magnetic fields are nothing but low and high pressure regions in the aether.
