ABSTRACT:
A disk antenna (10) has a base (12). The disk antenna (10) further has a hollow post (14) which is securely fastened at a bottom distal end to the base extending upwardly therefrom. The post (14) has a post base (14A). The post base (14A) is securely connected at a bottom distal end to the base (12) and rotatably connected at a top distal end to a bottom distal end of a post head swivel (14BA) which is rotatably connected at a top distal end to a bottom distal end of a post head (14B) which is securely connected at a top distal end to the dish (16). The disk antenna (10) further has a dish (16). The dish (16) has a dish plate (16A) having a dish cone (16B) centrally located therein. The dish (16) is securely attached to a top distal end of the post (14). The disk antenna (10) further has a primary antenna (18A) which is securely fastened to the dish (16). The secondary right antenna (18B) further has a secondary right antenna bracket (18BA) which functions to permit adjustment of the secondary right antenna (18B). The disk antenna (10) further has at least one secondary left antenna (18C) which is securely fastened to the dish (16). The disk antenna (10) further has a cable (20) electrically connected to the dish cone (16B) and the primary antenna (18A) and the at least one secondary antenna.
