WebNov 18, 2013 · A well-designed GNSS antenna is at least 10 decibels more sensitive to RHCP signals than LHCP signals at normal incidence. This reduces the magnitude of both the code- and carrier-tracking errors due to multipath interference. The exception is low-elevation signals, for which the antenna has very little polarization discrimination. ...
