The Brück aerial testing facility is a facility for testing aerials at Brück, south of Berlin. It was established in 1939.
On the Brück aerial testing facility there are two 54adj=midNaNadj=mid wood-framework towers built in 1963, made without any metallic parts and used for mounting aerials to measure their characteristics. One of these towers, the Messturm III, consists of two towers connected by a bridge on top, while the other, the Messturm II, is from conventional design.
A third wood tower, the former Messturm I, which was built in 1958, was destroyed in a fire in 1979.
