WRT Series

ANT-916-WRT-ccc

VSWR

Figure 12 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.
