ABSTRACT:
A guard (120) for an antenna (602) includes a base (206) defined between a front edge (209), a rear edge (211), and two lateral edges (213, 215). A front generally triangular surface (208) extends from the front edge (209) to a narrowed upper edge, a rear generally triangular surface (210) extends from the rear edge (211) to a narrowed upper edge, and two lateral generally triangular surfaces (212, 214), each having a narrowed upper edge, extend from their respective lateral edge (213, 215). The narrowed upper edges form an apex (204), which forms an opening (202). The surfaces (208, 210, 212, 214) at least partially define an internal cavity (304) that encloses a portion (604) of the antenna (602). The front surface (208) is at a first angle (α) relative to a mounting surface (117) and the rear surface (210) is at a second, larger angle (β) relative to the mounting surface (117).
