ABSTRACT:
A getter assembly is described which has an antenna mount in the form of a small bar placed along the diameter of an annular container. The antenna mount is formed in such a way as to touch the container only in areas near to the inner wall. In order to reduce to a minimum the points and the areas of contact between the antenna mount and the getter material container, the connection of these two elements is made by means of two diametrically opposite spot welds near to the internal wall of the annular container and longitudinally disposed along the mount.
The mounting bar is preferably furnished with a downwardly dependent support member for maintaining the getter assembly away from the wall of the cathode ray tube in which it will be located.
