摘要

An antenna rod, comprises an antenna lead passing inside the rod and a layer of polymer material outside the antenna lead. The antenna rod has improved characteristic features because the antenna lead has been immersed into the polymer material layer. The antenna rod is produced by inserting the antenna lead longitudinally in a cavity of a casting mold, which is substantially of the shape of the antenna rod and thereafter encapsulating the antenna lead with a polymer material layer. The antenna lead can be reinforced for casting by joining it with a support structure by winding the lead to form a helical coil around the support structure.
