A self-contained radio apparatus for the transmission of data includes a resiliently deformable patch, a resiliently deformable antenna carried by the patch, a post secured to the patch and upstanding from an upper surface of the patch, the post providing at an end remote from the patch a mounting for a radio device, and, electrical conductors extending from the antenna to the end of the post remote from the patch for operably connecting the antenna to a radio device mounted on the post. The radio apparatus is useful for attaching to objects that undergo bending stresses, such as tires.
