Overview
The CompleTech CA420O omnidirectional coaxial dipole antenna (SKU: CA420O) delivers reliable 360-degree signal coverage in the 405-440 MHz frequency range, ideal for industrial, telecom, and broadcasting applications. With a consistent 2 dBi gain and vertical polarization, it ensures optimal signal reception and transmission across its operating band. The antenna features a low VSWR of less than 1.5, minimizing signal reflection and maximizing transmission efficiency. Constructed with high-conductivity copper radiators and a durable ABS/FG PU foam radome, the CA420O withstands harsh environmental conditions, including UV exposure, moisture, and temperature fluctuations. Its omnidirectional design eliminates the need for directional alignment, simplifying installation and reducing maintenance overhead. The CA420O supports multiple connector options—N-, TNC-, and 7/16-female—for versatile compatibility with existing systems. Designed for easy mounting on 35-60 mm diameter poles, it includes a robust mounting mechanism to ensure stability under wind loads up to 47 N. With a compact and lightweight form factor, the CA420O is a cost-effective solution for applications requiring broad signal distribution without the complexity of directional antennas. Typical use cases include telemetry systems, mobile radio networks, and industrial IoT deployments where consistent, wide-area coverage is critical.
