WRT Series

ANT-916-WRT-ccc

Return Loss

Return loss (Figure 13), 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.

Peak Gain

The peak gain across the antenna bandwidth is shown in Figure 14. Peak gain represents the maximum

antenna input power concentration across 3-dimensional space, and therefore peak performance at a given

frequency, but does not consider any directionality in the gain pattern.
