This program displays proyections of the radiation-pattern total directive gain asociated surface from files created with NEC-2. User can select to view a proyection on XY plane (option 1) or on YZ plane (option 2). If YZ plane is selected then after the display is finished the proyection plane can be rotated over Z axis with < > keys. With option 1 the view point is from the coordinates (theta=0,,) looking to the origin. With option 2 the initial view point is from (theta=90,phi=0,) looking to the origin, with this option user can change phi with < > keys.
