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 this work took place, an L-Antenna was used, which was spun between the other tower and a small auxiliary wooden tower.
