An antenna device includes an antenna coil, a magnetic core, and a metal member. The first four bar linkage system is operably mounted on the frame and operably connects the transferring means to the frame to allow for back and forth movement of the transferring means along a path of travel about an instantaneously changing axis of rotation. A node comprises a multi-sectored antenna and a transceiver controller. An anti-tilt frame extends upwardly from the base beyond the second stop rail and angled toward the wall to prevent toppling of the panels.
