VSWR

Figure 3 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes

the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna

performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of

the percentage of transmitter power reflected back from the antenna.
