Overview

The CompleTech CA420C4 is an offset pattern collinear antenna designed for reliable wireless communication within the 405-440 MHz frequency range. This antenna delivers a significant 11 dBi gain, ensuring robust signal reception and transmission for critical applications. Its vertical polarization is optimized for specific communication setups. Constructed with a durable copper radiator and a UV-resistant ABS/FG radome with PU foam filling, the CA420C4 is built for longevity in demanding environments. The connector type is N-female / TNC-female, providing secure and versatile connectivity. It features a VSWR of less than 1.5, guaranteeing optimal signal integrity. Mounting is facilitated by an aluminum alloy bracket compatible with poles ranging from 35-60 mm in diameter, secured with stainless steel V-bolts and self-locking nuts. The antenna is DC-short circuited for lightning protection and operates reliably within a temperature range of -40ºC to +80ºC, with an IP67 rating for dust and water ingress protection. Key features include a radome-enclosed radiator, IP67 proof construction, and electromechanics molded within closed-cell PU foam. This antenna is ideal for telecommunications infrastructure, industrial IoT deployments, and security systems requiring dependable performance in the 405-440 MHz band.
