Abstract
An antenna assembly includes a stand having a convex outer surface positioned to intercept and engage a vehicle tire as the vehicle tire passes over the convex stand surface. The height and contour of the convex stand surface slows the rotational rate of the vehicle tire, and thereby a transmitting device carried by the tire, to a preferred rotational read rate as the vehicle tire passes over the convex surface. One or more antenna members mount to the stand proximal to the convex surface, each antenna having a directionally aimed tilted antenna field positioned to continuously receive data transmission from the electronic transmitting device as the vehicle tire passes over the convex stand surface at the reduced rotational read rate.
