Apparatus for heating a large parabolic microwave antenna reflector comprising metal tubing having electrical heating wire encased therein, the metal tubing being bent into a desired non-linear shape and being firmly attached to the convex rear surface of the reflector so that current passing through the conductor wire will heat the metal tubing which in turn will conduct heat to the parabolic reflector due to direct metal-to-meta1 contact between the tubing and the reflector.
