Overview
The CompleTech CA420X++ is a specialized cross-polarized Yagi antenna operating within the 405-440 MHz frequency range. This antenna is constructed with a durable copper radiator and features an ABS/FG, PU foam radome for environmental protection. It offers a dual/circular polarization capability, enhancing signal integrity and reducing interference in complex RF environments. The CA420X++ delivers a consistent gain of 10 dBi in both horizontal and vertical planes, ensuring robust signal transmission and reception. Its VSWR is rated at less than 1.5, indicating efficient power transfer and minimal signal reflection. The antenna is designed for versatile connectivity, supporting N-, TNC-, and 7/16-female connectors. Mounting is facilitated on poles with diameters ranging from 35 to 60 mm. With a wind load capacity of 120 N, the CA420X++ is built to withstand significant environmental stresses, making it suitable for critical communication infrastructure. This model is part of CompleTech's line of Yagi antennas, including variants like the CA420X, CA420X+, CA420XF2+, and CA420XF2++ which offer different gain levels and configurations within similar frequency bands. The CA420X++ is engineered for applications requiring reliable and clear signal propagation in the specified UHF band.
