What are the possible values for standing wave ratio?

Under ideal conditions, the RF voltage on a signal transmission line is the same at all points on the line; therefore, the SWR is 1. When this happens, the load uses all the RF power that reaches it from the transmission line. However, this optimum condition can exist only when the load impedances are identical and the load contains no reactance.

What is transmission coefficient?

The ratio of the amplitude of the transmitted wave to that of the incident wave is called the transmission coefficient. It is calculated by adding 1 to the reflection coefficient i.e., 1+r.
