Abstract
A microwave antenna has a circular wave guide feedhorn mounted above a reflector. An electrically insulating sleeve fits around the outer diameter of circular wave guide. A scalar ring is secured to the insulating sleeve. The sleeve isolates the ground of the circular wave guide from the reflector and scalar ring so that electrostatic charge accumulating in the reflector does not damage electronic components electrically coupled to the wave guide.
