After we announced our takeoff for Runway 6 we taxied onto the runway and began the takeoff roll.  We heard no other aircraft moving on the airport.  Right after rotation we saw an Aircraft Y taxiing across the end of the runway.  We missed the other aircraft by 40 to 50 feet vertically and 0 feet horizontally.  Both crew members believe there are many radio dead spots on the airport that prevent effective communication between aircraft.
Pilot reported a NMAC during takeoff and while using the CTAF frequency at COE airport.
