In this menu it is possible to specify the parameters for a Cartasian coverage plot. The plot displays the area wher the RX treshold is met together with a Strong Signal margin. Both plots have their own color specified.

The coverage produced by radio Mobile Online is a hybride of two polygons.
One is the area in wich the minimum signal to meet RX treshold is met.
This is the Weak Signal where: Rx treshold < x < Strong signal.
The Weak signal is calculated from: Rx treshold + Mobile antenna gain + Rx line loss.
The second area is the area in wich the signal is stronger than the Strong Signal: x > Strong signal.
The strong signal is calculated from: Weak signal + Strong signal margin.
The follwing imga shows a simplified coverage where all parameters are displayed:
This is a margin above the minimum signal to meet RX treshold in dB.
Select the HEX color code for the Strong signal color. The color is immediately displayed after a [TAB] to jump to the next field.
Use the Color Picker to convert colors in to HEX-codes ( In a pop-up window)

The transparency of the coverage polygons.
The maximum distance over which Radio Mobile Online will do pathloss calculations. The ranges are preset and can be choosen from by a pulldown menu.
The resolution of the prediction or bin-size of the calculation does affect teh detail of the presented image. A higher resolution will require more processing time. The resolution and so the calculation time can be selected here. A preset resolution is availabel form a dropbox.
