Usually a radio quiet zone has been installed around a radio astronomy station. The extent of this zone differs from station to station depending on the characteristics of each individual station.
The different kinds of European radio telescopes are listed below. To this the following note
should be taken into account:
Connected element radio interferometers are operated at:
Radio observatories which also operate as nodes of the Multi-Element Radio-Linked Interferometer Network, MERLIN:
Radio observatories which also operate as nodes of a VLBI network are:
