BS11-BL Air+ control with 9m loop antenna

Air+ controls allow for participants to punch the control from a distance, given they have the proper personal SI stick (SIAC). This control with a loop antenna allows the organizer to have a finish line up to 9m wide (either buried or above head height) and when competitors traverse across the antenna their time is recorded in the Air+ SIAC finger stick. Participants can cross the finish line at full speed (up to 30km/h), not having to slow down to insert their SI stick into the control.
