The RetroAntenna® weather resistant antenna cover is ideal for regions with high humidity or frequent rainy conditions. This rubber cover fits over the antenna motor to protect it from unwanted moisture, prolonging the life of the antenna in harsh conditions. To install the cover, simply remove the top nut, angled base, mounting base, and retainer cup; then slide the rubber cover over the antenna motor and secure it to the base of the mast with a zip tie.
