A radio element in Xirio represents each of the radiating elements in a distributed antenna system. The properties dialog of the radio element of a transmitter is similar to that of the transmitter radio parameters.

•Name

•Coordinates. The location of the transmitter is configured through the coordinates of a site (longitude and latitude). These can be entered manually, through a catalog element by pressing inspect or by selecting a point in the viewer with the mouse through the pointer icon.

•Antenna. It is defined from its radiation pattern. By pressing you can access the antenna configuration window.

Xirio configures a valid antenna by default to calculate the study, based on the service selected in it. You can also create a new antenna by eliminating the existing one by pressing and manually entering the antenna's own data.

•Antena height. Height in meters of the radiating system used.

•Azimuth. Horizontal pointing, in degrees, of the transmitting antenna (possible range from 0º to 359º).

•Mechanical downtilt. Vertical mechanical pointing, in degrees, of the transmitting antenna (possible range from -90º to 90º). Positive values represent an antenna tilt down, negative values represent a tilt up.

•Electrical downtilt. Vertical electrical pointing, in degrees, of the transmitting antenna (possible range from -90º to 90º). Positive values represent an antenna tilt down, negative values represent a tilt up.

•Feeder, length and losses.

•Losses. Due to passive elements such as connectors, cables, diplexers, etc.., except for feeder losses previously contemplated.
