Good question, I've been wondering for some time now how to build a telepad. I build the Raid Teleporter or whatever by accident, but it didn't help at all.
So 2 questions to the helpful people that posted earlier:
1) What in the hell is the raid teleporter and what does it do?
2) So all I need to do to get a REAL teleporter that takes my SG members places, is build a workbench? Do you make it out of salvage, or... can somebody elaborate more on exactly what the process is for crafting such an item?
