The design, construction, and testing of a gravitational antenna for use at 3 mdegreeK is discussed. New developments include the ''weak spring ring'' and ''resonant ring'' mounting systems, and a highly sensitive magnetic detector with remotely controlled continuously variable coupling to the antenna. For a prototype aluminum antenna a value of Q=4 x 10/sup 6/ was obtained at 4.2 degreeK and calculations predict a sensitivity sufficient to detect thermal oscillations at 3 mdegreeK.
