Does that transmission line, which connects your antenna and transmitter, seem like a mystery to you? Or perhaps your have other questions: Just how much of the transmitter's rated output power actually gets to the antenna? How much power is consumed by the line itself? Just what is the input impedance of the antenna? Or, what is the input impedance at the transmitter end of a transmission line when the antenna is connected to its other end? Why does my tuner seem to work better on some bands than others? What is the effect of high transmission line SWR? Should I be concerned about high SWRs?...
