Help in the Assault on Fort Independence mission (Fallout 4)

build the generator next to the radio transmitter, press the "down" button once, aim at the generator and stretch the wire between them with the space bar.

I did this: I put 2 generators of 5 energy each, connected it with a power line support and as a result they give 10 energy, then you pull from the support to the transmitter

Thank you. I figured it out myself
