In the last years several experiments have been devoted to the search for CMB polarization, but no positive detection has been obtained so far. In fact the expected degree of polarization is very low and its detection is extremely difficult. Very special design and system stability are necessary to reach sensitivities of one part in 106 or greater. Here we present the Milano polarimeter, a 33 GHz correlation system which can be used for detecting both linear and circular polarization. It has been designed to operate at large angular scale (7°-14°) from ground. In this contribution we describe the experience acquired so far during observations and the solutions adopted to improve the sensitivity. .
