How does a Radio Antenna Work?
I'm trying to get a grasp of the physical mech.
You generate an AC signal on a conductor (i.e. at 30mhz)
The free electrons on the skin of the conductor osc. back/forth at 30mhz.
The acceleration / decleration of the free electrons causes photons to be released from the free electrons (Photons being the E field)?
The acc / decl will only be large enough to cause photons to be released, if the conductor is long enough to accommodate at least 1/4 wavelength?
