Piece of "Freya" German radar equipment (13 items).

The Freya FuMG 39G was the first operational early warning radar defense system. In 1938 and before the start of the Second World War, eight of these units had been delivered by GEMA and deployed along the German border. The early versions had a range of 60 km which was later increased to 120 km, operating at about 125MHz. Bearing accuracy was improved by a 'split' technique similar to that used in the British ASV II equipment.
