Inbound and departing traffic into the many airports of the Dallas/Fort Worth area is neatly sorted along specific routes and altitudes that are based on navigation fixes on three VOR navigation beacons that are more or less arranged across the DFW area- one in Dallas, one at DFW Airport, and one in Fort Worth.
This is VOR/DME antenna named "COWBOY" in Dallas just southwest of I-35E and Royal Lane.
The VOR in Fort Worth is named RANGER and the VOR at the DFW Airport is named MAVERICK.
