CA350N4

The CompleTech CA350N4 is a specialized cardioid pattern notch antenna engineered for precise signal management within the 336-364 MHz frequency band. This antenna offers a substantial 8 dBi gain, ensuring robust signal reception and transmission capabilities. Its vertical polarization is critical for specific communication system requirements. The CA350N4 features a durable construction, with a UV-resistant ABS/FG radome filled with PU foam, providing excellent environmental protection and IP67 proofing. The internal radiator is constructed from high-conductivity copper, contributing to optimal RF performance. A key specification is the low VSWR of less than 1.5, which minimizes signal reflection and maximizes power transfer efficiency. Connectivity is handled via a versatile N-female/TNC-female connector, ensuring secure and reliable interfacing with associated equipment. The antenna is designed for straightforward mounting on poles with diameters ranging from 35 to 60 mm, utilizing an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. Its design also incorporates features for lightning protection via a DC-short circuited feed point, and it operates reliably across a wide temperature range of -40ºC to +80ºC. The combination of durability, light weight, and low wind load (144 N) makes the CA350N4 suitable for various outdoor industrial and telecommunications installations where precise frequency filtering and directional reception are paramount. Integrated impedance compensation and an RF choke further enhance its performance characteristics, making it a dependable choice for applications requiring focused signal reception in a specific frequency notch.
