After landing, the pilot taxied to the fixed base operator to park. As he approached the parking ramp, a lineman stood in front of a tie-down spot and raised both hands in the air signaling to the pilot where to park. The spot was next to a parked jet. The pilot said that while taxing to the parking spot he was concentrating on staying clear of the jet and did not see a light pole located at the edge of the ramp. The right wing struck the pole resulting in structural damage to the wing.
