There are three transmitter sites in the system:
The master transmitter at Lake Kickapoo is said to be the most powerful continuous wave (CW) station in the world, at 768 kW radiated power. Overhead imagery (see coordinates given above) of the Gila River and Jordan Lake sites suggests that the original design called for antennas of twice the present length with, presumably, greater radiated power.
There are 6 receiving stations:
The receiving stations at Elephant Butte and Hawkinsville are considered to be "High Altitude" stations with longer and more complex antenna systems that are designed to see targets at higher altitudes than the other four receiving stations.
