I found it a two person job, plus a crane operator. One person does the disconnect. One holds the base of the mast away from the hands of the person working on the wires. Crane operator takes directions from only one designated person...
Lift mast about 1 foot, enough to see beneath the mast for the wires. pull them out from inside the mast. disconnect, then the designated control person gives the crane operator the signal to raise the mast.
Alternately, some masts have an access panel ot the base. You remove the panel and the wires should be right there.
Take it slow and deliberate and you should be fine.
