SPINNER manufactures and supplies matrix systems in RL 100-230 (50 Ohm) for shortwave and an RF power of 250 kW for BBC’s station in Thailand for 4 transmitters and 14 antennas. The switch matrix can route the transmitters to any antenna or the dummy load. Switching errors are prevented by a very elaborate electrical and mechanical safety system. Other major stations are established in Hong Kong (1986), Seychelles (1987), Skelton in the UK (1993) and Oman (2001).
This new production line automatically solders and assembles jump wires, resulting in superior electrical and mechanical properties and considerably better passive intermodulation values than those of manually assembled connectors.
The SPINNER CAF® cable clamps can be installed quickly and reliably in a single step to provide effective protection from moisture and soiling. Installation typically takes less than two minutes (for a time saving of about 80%!) since the connector is supplied in one piece and only needs to be attached to the prepared cable.
The Jindalee Operational Radar Network (JORN) is used to monitor Australia’s northern coastal area. It comprises an antenna array that includes a large network of alternately operated individual antennas in varying phase positions. This makes it possible to change the direction of the array’s main beam.
By getting its quality management system certified as complying with DIN EN ISO 9001, SPINNER achieves a major milestone. We also step up our efforts to protect the environment, leading to certification according to DIN EN ISO 14001 on the environment in 1999 and DIN EN ISO 50001 on energy in 2016.
SPINNER has a long tradition of promoting young talent: the Dr. Georg Spinner Radio-Frequency Award is bestowed for the first time in 1992. Every year since then, this accolade has been gone to a graduate of the Technical University of Munich for an outstanding dissertation. The award comes with a purse of 3,000 euros.

In 1971, SPINNER holds a major event to celebrate the 25th anniversary of its founding. By this time, the company already employs 500 people.
In cable television, the signals for the picture and sound are transmitted to a receiver via a broadband coaxial cable. SPINNER creates special connectors and fittings for this purpose, which over the years will be repeatedly adapted in response to new technical developments.
The company trained its first apprentice as far back as 1953. In 1970, the training workshop moves to Westerham, where some 15-20 new apprentices still begin learning industry professions each year.
These first RF rotary joints were mainly used in stationary radar systems. Today, SPINNER rotary joints can be found everywhere: in applications above and below water, on land as well as in the air and even in satellites.
SPINNER supplies the first coaxial transmission lines for transmitter matching (with 250 kW of power at 200 MHz) for the Proton Synchotron (PS) of CERN, the world’s largest particle physics research center.
The arrival of color TV in Germany is announced on August 25, 1967 during the International Radio Exhibition in Berlin. SPINNER has developed audio/video combiners that are used by the broadcasting stations.
