11144 Radiocommunicata           Discovered 1997 Feb. 2 by J. Ticha and M. Tichy at Klet.
The twentieth century can be called the age of communication. The staff of the Klet broadcasting tower, providing radio, television and radio-relay connections to south Bohemia since 1959, embodies the spirit of communication.
