The PALS PDA-120 is a fully motorized 1.2-meter Gregorian offset antenna system, expertly encased within a perfectly shaped carbon fiber POD. This design offers ultimate protection for both the antenna and BUC against harsh weather conditions while simultaneously enhancing vehicle aerodynamics. Beyond its rugged exterior, the system delivers exceptional performance through its precision-crafted carbon fiber reflector and advanced Dual Optic technology. This combination ensures remarkably low sidelobes and superior cross-polar discrimination, guaranteeing reliable signal quality even in the most demanding operational environments.
The antenna's lightweight construction and compact, low-profile form factor enable seamless integration onto any vehicle platform. This makes the PDA-120 the ideal solution for rapid news gathering (SNG) with broadcast-quality signal acquisition, VSAT applications for disaster relief operations, secure corporate networks, and robust military satellite communications. Wherever your mission demands connectivity, the PDA-120 ensures robust, high-performance communication capabilities.
