The FM and TV mast Katowice / Kosztowy (RTCN Katowice / Kosztowy) is a 358,7 metre tall guyed mast for FM and TV situated at Mysłowice - near Kosztowy, Poland. It replaced the TVP Katowice Mast which was dismantled in the 1970s.
The TVP Katowice Mast which it replaced was a 225-metre-high guyed steel framework mast with a triangular cross-section near Katowice, Poland. It was not the transmission site for the medium-wave frequency 1080 kHz. This frequency is transmitted by the transmitter Koszęcin.
The FM and TV mast Katowice / Kosztowy is since the collapse of the Warsaw radio mast the tallest structure in Poland. It was inaugurated on June 23, 1976. Originally its height was 269 metres. In 1987 it was converted to its actual value.
