Radio tower 3SM-U81

Radio Tower 3SM-U81 is a location in the Commonwealth in Fallout 4. The tower is the source of three signals, Greenbriar Radio Signal, automated radio alarm and Nautical Radio Signal.

Layout
A large radio tower atop a hill is surrounded by 3-4 bloodbugs. Around the base of the tower are the scattered remains of a trading caravan with no loot of significance. The relay terminal has an unlocked computer with the option to "Extend satellites to amplify signals in the surrounding area". Activating that will get you several radio signals that weren't available in the area before. From the tower you can see just to the north a building with a moving searchlight. Inside there's a bed and an expert computer terminal, that has protectron controls and spotlight controls. The road just to the north is a patrol route for various enemies.

Appearances
Radio Tower 3SM-U81 only appears in Fallout 4.
