At the beginning of November 2004 aerial maker Nippon Antenna Co. Ltd. (EU) formerly opened its Euro¬pean Test Center in Northern Germany. The new radome that protects the test unit has a diameter of 26.14 meters (86 ft.) and is manufactured almost entirely from sandwich composites. It will be used to test the next generation of complex automotive aerial systems.
Often this type of construction uses multiple-segments that are bolted together via flanges on the edges of each panel. For optimum dielectric properties, Nippon Antenna required a dome that did not have any metal components and had a constant ‘wall’ thickness throughout.
The solution proposed by Hahlbrock GmbH and accepted by Nippon Antenna was the production of 86 Divi¬nycell-cored sandwich composite panels that are glued together using a tongue and groove system thereby creating a seamless construction.
