 of lattice steel, which is groundfed and therefore insulated against ground. This mast, which has a rectangular cross section, was perhaps built in 1936, but used until 1963 at another site.

In 2001 the Hirschlanden transmitter was modified for simultaneous broadcasting on two mediumwave frequencies, for 1143 kHz with 10 kW output power for AFN and for 738 kHz with 5 kW output power for private radio companies. Therefore the tuning house was replaced by a new one with a switch that allows the mast to be used for 738 kHz and 1143 kHz as well. The mast itself received a horizontal crosspiece on its top as roof capacitance, making it more efficient for 738 kHz.
