coefficient
2X 2 is the coefficient
The coefficient is the number that multiplies a value. For example, the coefficient of 4x is 4. If n+3 is in brackets in the form (n+3) then the coefficient is one. If not the the coefficient of n is also 1.
The reflection coefficient is related to Voltage Standing Wave Ratio (VSWR) as follows: Reflection coefficient = (VSWR - 1) / (VSWR + 1) The reflection coefficient provides a measure of the strength of the reflected wave compared to the incident wave in a transmission line system.
for an ideal matched transmission line, vswr is 1 and reflection coefficient is 0
the voltage standing wave ratio is defined (1+p)/(1-p), where p is the the reflection coefficient magnitude. p = 1 for an open circuit, therefore the VSWR will approach infinite.
VSWR on a line is infinite when the far end of the line is perfectly open or perfectly shorted,i.e. the line is terminated in an impedance of exactly zero or exactly infinite, AND the lineis perfectly lossless.Under those conditions, the reflection coefficient is 1.0 and the return loss is zero.

yes
The reflection coefficient is a measure of how much of an electromagnetic wave is reflected at a boundary between two materials with different properties, such as impedance. It is calculated as the ratio of the reflected wave amplitude to the incident wave amplitude. The reflection coefficient is typically used in the analysis and design of RF/microwave circuits and antennas.
It is 0.170
The range of the reflection coefficient is from -1 to 1. A value of -1 indicates perfect negative reflection, meaning all incident energy is reflected. A value of 0 indicates no reflection, where all energy is transmitted. A value of 1 indicates perfect positive reflection, where all incident energy is reflected back.
VSWR is a ratio which represent the efficient performance in a radio emittion.
