Voltage Standing Wave Ratio or VSWR is an efficiency value of cable transmission from Power Transmitted along the cable for example cable feeder,jumper,waveguide, or other transmited cable.
VSWR given by formula :
VSWR = Vmax/Vmin = (1+p)/(1-p)
VSWR will have 3 possible value :
1. VSWR : -1 if the cable is short circuit
2. VSWR : 0 or no reflection, or no Power Loss, or Power Transmitted from Transmitter 100% Transmitted without loss Power in cables, this is the ideal value but it is very difficult to find this value in the real life.
3. VSWR : +1 the ideal value also or more, this is the most value we are looking for +1,.., if we could find for example VSWR 1.1 in the cable so we could said that the cable is in good quality for Transmitted the Power with small losses Power. In this is the common value we are seen in real life.
