Soelvesborg Twin Towers

From Wikipedia, the free encyclopedia

The Soelvesborg Twin Towers are two 135 metres grounded lattice steel towers used as transmitting aerial for the foreign service of Radio Sweden on the mediumwave frequency 1179 kHz. The Soelvesborg Twin Towers are close to the coast of the Baltic Sea and allow the transmitter a perfect grounding for its transmission toward Central Europe. The aerial consists of four wires which are connected with the tower construction at half height. This construction allows grounding for the towers.

Transmitter: 1x600 kW Telefunken S 4006 Antennas: 2x135 framework antennas (1 meter over sea level) Main directions: 65° & 255° The station is reduced in south direction and gives only 400 kW in that directions. It's because of sharing frequency with other stations. In north direction the power is also reduced by the ground subdue.

Feeded power (PEP): 600 kW Beamed power (ERP): 2000 kW in main directions

Gain: 3,7 dB

Modulation- and final tube: 2x TH558 Feeding tube for the final tube: 1x TH561 Efficiency: 72%
