Two transmitter sites are located in Bechar: the LW station ( max. 2000 kW, 153 kHz ) and the MW station ( 400 kW, 576 kHz ), which have seperate transmitter buildings. The spacing between the stations is about 1.5 km.
The MW antenna consists of three masts. Only the centre mast is fed. Director and reflector are not fed, the director is grounded and the reflector is tuned by a coil. The height of the triangular masts is 108 m, they have just one level of stays holding the masts at a height of 75 m.

The plot above shows lines of equal field strengths (63 dBuV/m) for different transmitter powers.
The field strength of 63 dBuV/m is recommended for a good reception.
Please be aware that the radiation pattern and the partly different ground conductivity is taken into account.
