Abstract
A termination for a coaxial transmission line wherein an elongated central conductor is located in an enclosure or housing and is surrounded by a plurality of elongated resistor tubes. The central conductor is connected to the inner conductor of the transmission line and the resistor elements are connected to the outer conductor. The housing defines an inner flow chamber and a plurality of outer flow passages surrounding the inner flow chamber with the upper ends thereof communicating with the upper end of the inner flow chamber. A centrifugal blower is located at the bottom of each of the outer flow passages to generate an air flow upwardly and then through lateral ports into the upper end of the inner flow chamber, whereupon a flow proceeds downwardly in a turbulent vortex through the inner flow chamber to cool the resistor elements.
