Abstract

Contamination at the exciter of a parabolic antenna can lead to impaired signal quality, or even system downtime. A parabolic antenna is described which in addition to a parabolic reflector and an exciter has a rinsing device, which is configured so as to rinse and clean the exciter with rinsing agent or protect it from contaminants. Herein, the rinsing agent is injected, dropped, or else blown from a rinsing outlet in an outlet member at the parabolic reflector onto the exciter. Mounting the rinsing outlet directly to the parabolic reflector allows for the exciter to be cleaned from the parabolic reflector.
