An Axial-Flow Resnatron for UHF

A new design for a resnatron based on the axial flow of the electron stream has resulted in the development of a tube for uhf. The tube has been tested up to 29-kw cw power output at 420 mc with efficiencies from 45 to 75 per cent and power gains in excess of 10 db. The novel and general features of the mechanical design are described and the performance characteristics are given in curve and tabular form.
