Heliport where is took off, OL16, is 1150' MSL KOJA is 1600' MSL. Near the accident site, 2O8, MSL is 1600. The ground elevation rose as the flight continued

Aircraft flew at 1500MSL for probably 6-7 minutes then climbed to 1700MSL for the rest of the flight.

If this is correct, it never flew more than 350' AGL and steadily lost altitude above AGL. Got low enough to hit wires or anything else.
