A.17.14.3.2 Input parameters


The input parameters for the three site-general propagation models from ITU-R P.1411-11 are shown in SEAMCAT GUI in Figure 1 and defined in Table 1. The remaining parameters (such as frequency, Tx/Rx antenna heights and distance) are taken directly from the Tx/Rx local environments and SEAMCAT workspace.
