VSWR = voltage standing wave ratio = ratio of the maximum voltage to minimum on a line
= VSWR = Emax / Emin = Imax / Imin
Reflection Coefficient is the ratio of reflected voltage to incident voltage. = ZL - ZO / ZL + ZO
3M uses RA as the symbol for the coefficient of retroreflection.

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.
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.

The reflection coefficient is used in physics and electrical engineering when wave propagation in a medium containing discontinuities is considered.A reflection coefficient describes the amplitude of a reflected wave relative to that of the incident wave.In telecommunications, the reflection coefficient is the ratio of the amplitude of the reflected wave to the amplitude of the incident wave.
The magnitude of the reflection coefficient lies in the range of .

yes
It is 0.170

VSWR is a ratio which represent the efficient performance in a radio emittion.
VSWR=Zo-ZL/Z0+ZL since open circuited ZL=infinity so VSWR=infinity
