An assembly for adjusting an electrically regulated antenna includes a control device, a motor and a cable. The control device is connected with the motor via the cable, and a shielding material in the assembly for adjusting the electrically regulated antenna comprises alum-glass cloth tape. The shielding material composed of the alum-glass cloth tape is used for improving the electromagnetic shielding effect, particularly the passive intermodulation effect, of an electrically regulated antenna system. The invention further relates to a method for manufacturing the assembly for adjusting the electrically regulated antenna.
