Power supply for the loop can be brought by means of one of the columns - the impedance transformer to 50 Ohm will be directly on the loop. The signal will be further transferred by a short coaxial cable to [[en: |

- | There are two software packets used in online reduction of data from receivers, which could be used for data processing from multiple antennae. (There is more software for offline processing, but in such case, it is necessary to manipulate with enormously huge files). | + | There are two software packets used for online reduction of data from receivers, which could be used for data processing from multiple antennae.
