Berlin-Britz transmitter

The Berlin-Britz transmitter initially used a wire supported between two 30-metre (98 ft) tall wooden poles.

A second shortwave broadcasting aerial in the form of a dipole with whole length[clarification needed] was built in 1983.

A cross dipole aerial[clarification needed] for the medium wave frequency 990 kHz was built in 1978 to provide better coverage to the former East Germany for RIAS’ first channel.

This aerial for circular polarization[clarification needed] radiated vertically in the ionosphere and permitted good reception of RIAS 1 in the entire former East Germany.

This aerial was mounted on five guyed masts each with a height of 30.5 m (100 ft) and was shut down at the end of 1995.
