| This system can be used for sensitive continuum, spectroscopy, and pulsar observations. Additionally, it will be employed in search-programs for space-debris. Be aware, that this band may be influenced by RFI. The central horn has two circular polarizations, each of the outer six horns two linear polarizations. | This system can be used for sensitive continuum, spectroscopy, and pulsar observations.
