King WebIn review, this tutorial describes SWR or VSWR as a way to measure transmission line imperfections and efficiency. VSWR is related to the reflection coefficient. A higher ratio depicts a larger mismatch, while 1:1 ratio is perfectly matched. This match or mismatch arises from the standing wave's maximum and minimum amplitude. punta pennaWebThe voltage standing wave ratio (VSWR) is defined. VSWR is a measure of the reflected power on a transmission line. VSWR is a function of the characteristic impedance of the transmission line and the impedance of the antenna. VSWR specs (specifications) are introduced, along with formulas for mismatch loss and return loss in relationship to VSWR. barang kuasi
