Overview

The CompleTech CA420C3 is an offset pattern collinear antenna engineered for reliable communication within the 405-440 MHz frequency range. This antenna delivers a substantial 10 dBi gain and features vertical polarization, ensuring efficient signal transmission and reception for critical applications. Its construction includes a durable, UV-resistant ABS/FG radome with PU foam filling, protecting the high-quality copper radiator. The antenna is designed for a low VSWR of less than 1.5, minimizing signal reflection and maximizing power transfer. Connectivity is facilitated by versatile N-female and TNC-female connectors. The CA420C3 is built to withstand environmental factors, with a robust design capable of handling a wind load of 99 N. Mounting is flexible, accommodating poles with diameters ranging from 35 to 60 mm, utilizing an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. The feed point is DC short-circuited for lightning protection, and the antenna operates reliably in temperatures from -40ºC to +80ºC, with an IP67 rating for dust and water ingress protection. This antenna is an ideal choice for industrial, telecommunications, and public safety sectors requiring dependable wireless performance. SKU: CA420C3. Manufacturer: CompleTech. UNSPSC Code: 43221706.
