 ===== The Network =====
-An active airfield can build and upgrade one Direction-Finding station in one of its two build sites, paid from the airfield's storage (see [[components:airfields|Airfields]]). The network radius decides which nearby active sites act as relay sensors; it is not the station's listening range. If a site lies inside several networks, it is assigned to the nearest covering station and uses that station's level and calibration.

 | Level 1: Loop Direction Finder | 8 Lumber | 40 km | Airfield, Hubs and Cities | AAA |
-| Level 2: Adcock Direction Finder | 8 Steel | 55 km | Level 1 sites plus Factories | AAA, MANPADS and light camps |

-A level pays twice: it adds enemy types and it adds the sites allowed to listen for them. The station airfield hears further than a relay does, and a quiet emitter is heard less far than a loud one.
+Level 2 hears every enemy type, including everything a secure region still produces. Level 3 adds no new type; it pays in more relay sites, a wider network and much narrower cones. The station airfield hears further than a relay does, and a quiet emitter is heard less far than a loud one.
