 Clay used many words to say the signal propagates too far to get back to
 the radiator. It continues its journey away from the radiator.
 
 Radiation is really caused by exchange of energy between alternating
 magnetic and electric fields.  They produce each other when they
 alternate. Static fields don`t radiate. They soon fade away.
 
 J.C. Maxwell speculated that displacement current produces the same
 alternating magnetic lines as conduction current does. He was proved
 right.
 
 "Static" magnetic and electric fields move out into space when current
 flows and charge builds. When they are no longer changing, the fields at
 some distance have reached practical limits and stop expanding.
 Alternate these fields, and the fields can build each other and travel
 on and on.
