ANT-W63WS1 Series

VSWR

Figure 4 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.

Return Loss

Return loss (Figure 5), represents the loss in power at the antenna due to reflected signals. Like VSWR, a

lower return loss value indicates better antenna performance at a given frequency.
