By the measurement, we clarified the dependency of the XPD characteristics on the installation situation of a receiving antenna in a vehicle. We also evaluate the gain where the dual polarizations are ideally received and utilized. It is equivalent to the diversity gain of the maximal ratio combing. Therefore, using the measured data, we evaluated the gain of the space diversity and the polarization diversity. Based on these considerations, we discuss the effectiveness of the horizontal polarization focusing on the antenna installation
