For this tutorial lesson, use the Basic Link Wizard to create a vertically polarized half-wave dipole transmitter and a grid of isotropic receivers. Set the Grid Extents equal to 800m, and keep the default values of the other parameters, <i>i.e.</i>, a transmitter height of 10m, receiver height of 1.5m and receiver spacing of 5m. The transmitter base location point called "TXP" is originally positioned at (0, 0, 10m). Change its coordinates to (100m, 100m, 10m). At this time the transmitter is hidden under the terrain, and so are a large number of receivers.

To improve the reception, you can bring the transmitter to the edge of the plateau. Keep in mind that to move a transmitter or receiver, you need to move their associated based point sets. Change the coordinates of the base point "TXP" to X = Y = 30mm. Keep the original Z-coordinate of 10m. Now make Make sure to checkmark "Include edge diffraction" checkbox and run a new SBR analysis of the scene and visualize its coverage map. You will see that the valley region now gets considerable reception.
