The Radar tower is a sensor which will broadcast alerts on the frequency it is configured for.Both allies and foes are alerted.
The alert consists of a message containing name, settlement and coordinates of the detected unit.
Example:
Phadon [FREQUENCY] Radar ALERT! [NAME] [SETTLEMENT] at [COORDINATES]
Put this on the same frequency as the map to plot points for each detection.
Place on the same frequency as artillery to automatically strike anyone within detection range.
Radios set to the same frequency will also receive the broadcasts.
The radar will only expose those Players/Characters within its line of sight. As such, changing the height of the radar will increase it's effective range.
