Overview
The CompleTech CA420Y+++++ is a directional Yagi antenna engineered for reliable communication in the 405-440 MHz frequency range, delivering a robust 13 dBi gain for strong signal reception and transmission. This five-element Yagi antenna features a copper radiator for superior conductivity and an ABS/FG PU foam radome for environmental protection, ensuring long-term performance in harsh industrial, military, and public safety applications. The antenna supports both vertical and horizontal polarization, providing operational flexibility for diverse communication systems. With multiple connector options (N-, TNC-, or 7/16-female), it integrates seamlessly with existing infrastructure. The low VSWR (<1.5) minimizes signal reflection, while the 173 N wind load rating ensures stability in high-wind conditions. Designed for compatibility with 35-60 mm diameter poles, the CA420Y+++++ is a dependable solution for critical communication needs. Ideal for point-to-point links, repeater systems, and fixed-site applications where directional gain and durability are essential.
