*Name related to the coaxial use

Primary Focus
Cassegrain Focus

νLsky νHsky  : receiver RF band

The receiver labels have been assigned for identification purpose only (the letters p and c  stand for primary and Cassegrain focus, respectively).

The actually exploitable bandwidths may be narrower than the listed ones, due to the presence of RFI.

Multifrequency observations can be carried out with quick receiver changes (frequency agility).
