How does radio really work?
I'm studying to take the exam for a technician class ham radio license, and have been reading up for it. However, the book just gives practice, not theory. For example, it says that radio energy is carried down a coaxial, window, etc. cable between the two conductors, but it doesn't say how this actually happens or works. I know what radio does, but I'm a little lost when it comes to theory regarding its transmission, being carried in cables, filtering, SWR, etc. Answers are appreciated. Thanks!
