The present disclosure pertains to a rotationally triply symmetric three axis magnetic antenna system having substantial isolation among the three axes, including a three axis skew orthogonal magnetic antenna system and device utilizing the antenna system. The antenna system comprising three substantially identical magnetic antenna elements disposed symmetrically about a reference point such that the magnetic axes from the three antenna elements are orthogonal to one another in direction and do not intersect one another. The three antenna elements are positioned in a substantial cross coupling null from one another to minimize cross coupling. The arrangement yields packaging efficiency for compact electronic devices. A 1, 1, diameter embodiment is disclosed. A location system utilizing the antenna system is disclosed. Methods for producing the antenna are disclosed. A moldable triple coil holder for the antenna system is described.
