Ismaning Radio Transmitter

Ismaning Radio Transmitter

The Transmitter Ismaning is a large radio transmitting station near Ismaning, Bavaria, Germany. It was inaugurated in 1932. From 1932 to 1934 this transmitter (which replaced the Stadelheim Transmitter at Munich-Stadelheim) used a T-antenna as transmitting antenna, which was spun between two 115-metre-high free-standing wooden lattice towers, which were 240 metres apart. As this antenna had an unfavourable vertical radiation pattern, which produced much skywave resulting in a too small fading-free reception area at night, in 1934 a new antenna was installed. Therefore one of the towers was dismantled and rebuilt on a 39 metres high wooden lattice base. While these works took place, an L-Antenna was used, which was spun between the other tower and a small auxilliary wooden tower.
