Relay tower 1DL-109 is a location in the Commonwealth in 2287.


The relay tower sits atop a rocky hill, in close proximity to a water lock and a set of railroad tracks. Around the base of the tower is a terminal, which can be used to extend the tower's satellites, to amplify the signals in the surrounding area, acquiring three new radio signals for the Pip-Boy radio. Also, by the base of the tower, there is a broken utility Protectron, with randomized loot.


  • Boston City Works Beacon is 89 meters away and can be found by heading west towards the water lock and inside the small hatch in the operations building.
  • Distress signal (Relay tower 1DL-109) is 89 meters away and can be found inside a train car by heading south-southeast from the radio beacon until meeting the train tracks and finding a train with several feral ghouls. The fourth car along (blue car, turned on its side) has a hatch to enter the train, hidden behind a bush. It can be easily found, as it's the only bush touching the train on either side.
  • Garbled radio beacon is 208 meters away and can be found by heading due east from Oberland station until burning trees and a crashed alien spaceship are seen, then following the green blood trail to an unmarked cave at the UFO crash site.


The garbled radio beacon only starts broadcasting after reaching level 20.


Relay tower 1DL-109 appears only in Fallout 4.
