| This system is used for sensitive continuum, VLBI (especially 18cm), spectroscopy, and pulsar observations. Be aware, that this band may be influenced by RFI. It can be used in combination with a multi channel polarimeter of 8x4 MHz band width, and a total 40 MHz wide channel. | This system is used for sensitive continuum, VLBI (especially 18cm), spectroscopy, and pulsar observations.
