A base station antenna array comprises a ground plane and a parallel array of antennas above the ground plane. To avoid loss of image quality when the image is transferred into the plastic molding, the method for fixing images in plastic moldings after generating an image on an adhesive layer is characterized in that an image receptor layer of liquid plastic is applied to the image which, with or without an additional carrier, is generated on the adhesive layer. The charging method includes charging, by the charging device, the energy storage device with a voltage set value which is near a maximum allowable voltage value of the energy storage device. The trim die is retrofit by modifying existing apertures and adding additional aperture in required positions. A minimum cost tile is then selected as the point to which the Steiner point in the 2-path, if any, is to migrate. and higher; and a drop tube delivery conduit within the casing, the drop tube having radial exterior ribs which extend into the fluid return annulus formed between the interior wall of the casing and the exterior of the drop tube.
