VSWR 862.0 832.0 821.0 5 791.0 Figure 1 and Figure 2 provide 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.

The straight-cut RG-174 coax cable option allows the attachment of a 50-ohm RF connector or allows the cable to be soldered directly to a PCB, eliminating the need for a connector. The connectorized option provides a 1.32 mm coax cable terminated with a U.FL/MHF compatible connector for simplified manufacturing or for applications requiring the ability to disconnect the antenna. Counterpoise Quarter-wave or monopole antennas require an associated ground plane counterpoise for proper operation. The size and location of the ground plate relative to the antenna will affect the overall performance of the antenna in the final design. When used in conjunction with a ground plane smaller than that used to tune the antenna, the center frequency typically will shift higher in frequency and the bandwidth will decrease. The proximity of other circuit elements and packaging near the antenna will also affect the final performance. For further discussion and guidance on the importance of the ground plane counterpoise, please refer to Linx Application Note AN-00501: Understanding Antenna Specifications and Operation.

Antenna radiation patterns (Figure 9), are shown using polar plots covering 360 degrees. The antenna graphic above the plots provides reference to the plane of the column of plots below it.
