Methods, apparatuses, and systems for two-way satellite communication and an asymmetric-aperture antenna for two-way satellite communication are disclosed. The process includes simultaneously illuminating a plurality of measuring points on the material web with electromagnetic radiation, and imaging, through at least one optical device, the plurality of measuring points on one detection surface of at least one detector. The solid conductor has a first end, a second end, and a first conductivity between the first and second ends. The body is adjustably connected to the nose. There is also provided a use and kit.
