SLOCAT              The site location (e.g., country, city, province, district, state) should be entered to assist in the identification of the site.  The location will be printed on most of the      output from the program.                                                                                                
SDESC               The description  entry is  used to make a notation about thesite under study. The description will be printed on severalreports generated with this software to identify this       site.                                                                                                                   
SLON                Enter latitude and longitude (in degrees, minutes, seconds) in order to compute distances or to perform other           engineering calculations regarding the site.                Note that if you are using both geographic coordinates and  UTM coordinates, changing the latitude or longitude will    cause the UTM zone and coordinates to be recomputed.                                                                    NOTE: If you are working with UTM (Universal Transverse     Mercator) coordinates, you can ignore this field. The       latitude and longitude will be computed automatically when  you enter the UTM zone and coodinates.

SUTMZ               Enter the UTM (Universal Transverse Mercator grid) zone for the site. If the site is in the southern hemisphere, the    zone must be entered as a NEGATIVE number.                                                                              NOTE: If you are not working with UTM coordinates, you can  ignore this field. The UTM zone and coordinates will be     computed automatically when you enter the latitude and      longitude.                                                                                                              
SUTMN               The UTM coordinates (Universal Transverse Mercator grid)    should be entered in kilometers.                                                                                        NOTE: If you are not working with UTM coordinates, you can  ignore this field. The UTM zone and coordinates will be     computed automatically when you enter the latitude and      longitude.                                                                                                              
SUTME               The UTM coordinates (Universal Transverse Mercator grid)    should be entered in kilometers.                                                                                        NOTE: If you are not working with UTM coordinates, you can  ignore this field. The UTM zone and coordinates will be     computed automatically when you enter the latitude and      longitude.                                                                                                              
SELEV               The elevation entry should be the site elevation as shown onan accurate topographic map, such as the USGS 7-1/2'' quads.If you enter an elevation of zero (0), the zero will be     replaced during the next radial data extraction session withan estimated elevation from the data base. You should NOT   rely on this interpolated value for detailed site or path   analysis. If you enter a non-zero site elevation, the value will not be replaced.                                                                                                   
SCRAGL              The antenna center height above ground level (AGL) is used  to compute HAAT values, and line of sight and Fresnel zone  obstruction shadowing.  The value entered should be the     center of radiation for the antenna.
