The relay tower consists of a radio tower and a terminal used to activate and extend the satellite dishes on the tower. After activation, three new radio signals will become available in the Pip-Boy radio at specific locations in the Glowing Sea.
- Distress signal (Relay tower 0DB-521), coming from the south of the two caves to the west of the tower.
- Skylanes 1665 Mayday, the last conversation between a pilot and a control tower after an engine fire, coming from Skylanes Flight 1665 to the southwest from the tower.
- Unintelligible radio signal, coming from the Hopesmarch Pentecostal church to the northwest.
Relay tower 0DB-521 only appears in Fallout 4.
