In this case, the geometry section consists of twelve codice_4 elements making up the antenna. Each element is longer than the last, and to maintain accuracy, the later elements are divided into more segments. All measurements in NEC use metres, so the first element is 2 metres wide, running from -1 to 1. The codice_13 line indicates the end of the geometry section. At this point, NEC scans the geometry for overlapping endpoints, which it then connects together to make a single longer conductor. The codice_13 line also has a single input that indicates whether a ground plane is present; in this example, it is not specified, so the antenna is located above a "standard ground".
