An antenna assembly that includes a bobbin including arcuate first and second bobbin portions positioned about a tool mandrel. A protective layer is formed about the first and second bobbin portions, and a cover occludes a portion of an axially extending gap defined between the first and second bobbin portions to prevent the protective layer from extruding into the gap.
