Very interesting pictures, thanks for sharing.
2cm was a very short wavelength in those days, pictures of such devices are very rare.

The church is the Wallfahrtskirche Maria Himmelfahrt in Hohenpeissenberg.
In theory it is possible that the church or adjacent buildings were used as 'radar-lab'.
Radio-beam is also possible.
Note the platform on the church-roof and cable in the foreground.

Pictures of Wurzburg Riese and Kdo Ger 40 were taken at a different location.

All Wurzburg radars operated around 560Mhz which is approximately .5m wavelength. It had a 2-microsecond pulsewidth, which is about standard for a search/tracking radar. The smallest wavelength (highest frequency) generally used in the war, and only by the Allies, was 3.2cm or about 9000Mhz = 9Ghz. This frequency and higher (smaller wavelengths) are greatly attenuated by water molecules, e.g. clouds, and no radar with a smaller wavelength than 3.2cm was fielded during the war.
