# What is the reflection coefficient on a transmission line at a resistor halfway?

 P: 55 1. The problem statement, all variables and given/known data If I have a coaxial transmission line, with a resistor halfway through, and another resistor at the end, how do I calculate the reflection coefficient for the spot where the resistor is halfway? Here is a diagram of what I mean. Dashes and dots are are the lines, and } are resistors. ---------- ....}a....}b 2. Relevant equations $$\Gamma_{L} = \frac{Z_L-Z_o}{Z_L+Z_o}$$ 3. The attempt at a solution I am pretty sure the formula I am supposed to use is $$\Gamma_L = \frac{Z_L-Z_o}{Z_L+Z_o}$$. What I am not sure is what value to choose for $$Z_L$$. Do I take $$Z_o$$ in parallel with $$R_A$$?
