Center of Ground Plane

The charts on the following pages represent data taken with the antenna oriented at the center of the

ground plane, as shown in Figure 4.

VSWR

Figure 5 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.
