Note that these all need power, so you'll have to build a number of generators. Then build the other three components: the Beam Emitter, the Relay Dish, and the Console. The faction scientist will help you after you've built the first section, the Stabilized Reflector Platform. The Pip-Boy is programmed to point out the likely locations of these items.

If you don't have these three items, don't worry. All the components use common items such as copper, steel, and rubber, but you might have to seek out three less common items: a military circuit board, a sensor module, and a biometric scanner. Hopefully by now you will have scavenged a lot of building parts to fulfill all the requirements for the four sections of the teleporter. This section will show you all the necessary components. Bring up the Workshop menu and a ‘Special' category will appear. The Minutemen's settlement at Sanctuary Hills has number of such lots.

Whether you decide to build the teleporter with a faction or not, you first have to start with a large empty lot in a Settlement. When you express your need to have a Signal Interceptor built, the faction leader will tell you to talk to the faction's tinkerer or scientist. Whichever faction you choose, you'll need to complete the first two quests pertaining to each faction, one of which being the quest where you encounter the faction. That would be Paladin Danse from The Brotherhood of Steel, Preston Garvey from The Minutemen, and Desdemona from the Railroad. To get help from a faction, talk to the leader of your faction of choice. The benefit of getting help from the respective scientist of any of the three factions is that they'll give you advice on how to put the teleporter together. To build the Signal Interceptor, you have four options:

Virgil will give you the plans to build a Signal Interceptor, which will allow you to teleport to The Institute and rescue Shaun. After Tom takes a look at the chip, fast travel to Virgil's lab in the Glowing Sea.
