FuMG 41/42 Mammut radar. This coupled two Freya stations together, and used eight Freya antennae in one array to increase range. This was the first phased array radar: the array was fixed, but the beam could be steered electronically one degrees in front and back, leaving an eighty degree blind spot on the sides. Range was 300 km (186 miles), at a frequency of 120 to 130 MHz and peak power was 200 kw. First built in 1944 by GEMA, only a few stations were operational before the war ended.
