[1] The mast was designed for extreme height in order to broadcast Communist propaganda around the world, including to the remotest areas such as Antarctica.
Due to the mast's height, listeners from all over the world could tune in to Polish radio broadcasts, including those in remote places such as Antarctica.
[2] The mast's location, which was finalised to be in Gąbin, was chosen because of its high soil conductivity and the need for a position in the centre of Poland.
[9] A large amount of research was utilised to decide where to build the mast, which included factors such as soil resistance, ownership of property, and the quality of infrastructure (especially roads).
The Raszyn transmitter was designed to cover the Eastern Borderlands, and so Polish authorities did not consider reception in the Recovered Territories.
When it became evident that Raszyn could not provide coverage to the entire country, the station received an increase of power to 500 kW, but this too failed.
In the late 1960s it was decided to construct a new central transmitter at the geographical centre of Poland (post-WWII borders).
The elevator was designed by Alimak Hek [sv], a Swedish company, and took 45 minutes to reach the top.
An area for maintenance supplies was present, in order to transport materials such as lightbulbs for the aircraft warning lights.
Static electrical charge can build up to high values, even at times of no thunderstorm activity, when such tall structures are insulated from ground.
At the top there was a flashing beacon consisting of two lamps of 1,000 W.[14][15] A 600 metres (2,000 ft) long special overhead radio frequency transmission line of 120 ohms was used to transfer the signal from the transmitter building to the mast.
When high-voltage power was switched on, the transmitter was protected by two locked doors and crews were informed by way of illuminating a red lightbulb.
The station, which had an area of 65 ha (160 acres), also had a 76 metres (249 ft) lattice tower of rectangular cross-section close to the transmitter building.
Six small towers were erected around the periphery of the station's grounds in order to support aircraft warning lamps where the guy ropes were located.
[19] A lack of equipment and training of maintenance teams led to a severe degradation of the mast's condition by the late 1980s.
The facility also had a complement of guards, hired directly by the Ministry of Interior, mainly from the local population of Konstantynów.
After the main cable had been disconnected and before the temporary ones could be connected, a gust of wind twisted the temporarily unmoored tower, pulling loose the other guys.
[26] The transmission line was also unaffected, but it was dismantled shortly after the collapse of the tower, leaving only the sustaining poles in place.
[20] The construction coordinator and the division chief of the company responsible for maintaining the mast were found liable for the collapse, and both were sentenced to 2.5 years in prison.
[1][29] After the collapse, Polskie Radio used the old Raszyn transmitter with its 335 metres (1,099 ft) mast near Warsaw, which had been used since 1978 for daytime transmissions of a second Polish broadcasting service programme in the longwave range on the frequency AM-LW 198 kHz, for transmissions on AM-LW 225 kHz with a power of 500 kW.
Several other locations were considered, but due to the continuing resistance of nearby inhabitants (backed by the Solidarity trade union), planned mast height and transmitter range were both greatly reduced, and an old military site just southeast of Solec Kujawski was chosen.
[33] There were once again protests in this location, but tensions were eased when Polish Radio donated PLN 3.5 million towards the development of the local community.
[34] There, a new longwave transmission facility was built in 1998–1999, with a transmitter of 1200 kW output power for the frequency AM-LW (long wave) 225 kHz.
[36] Except for the mast and the radio-frequency transmission line that led to it, nearly all components of the facility remained in place, unused and slowly deteriorating.
