CA380N4

The CompleTech CA380N4 is a specialized cardioid pattern notch antenna engineered for precise signal management within the 365-395 MHz frequency band. This antenna offers an 8 dBi gain and vertical polarization, ensuring focused signal transmission and reception for critical communication links. Its design incorporates a UV-resistant ABS/FG radome with PU foam filling, providing robust protection against environmental factors and contributing to a lightweight construction with a low wind load of 140 N. The radiator is constructed from copper for optimal conductivity and signal integrity. Featuring a low VSWR of less than 1.5, the CA380N4 minimizes signal reflection, maximizing power transfer efficiency. Connectivity is facilitated by a versatile N-female/TNC-female connector, compatible with a wide range of radio equipment. Mounting is designed for poles with a diameter of 35-60 mm, utilizing an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts for secure installation. The antenna is DC short-circuited for lightning protection and operates reliably across a wide temperature range of -40ºC to +80ºC, with an IP67 ingress protection rating for dust and water resistance. Key features include a field-adjustable pattern and optional beam tilting, allowing for fine-tuning of its directional characteristics. The H -3 dB beamwidth is 229º, and the E -3 dB beamwidth is 23º, with a front-to-back ratio of 30 dB, underscoring its directional performance. This antenna is ideal for applications requiring precise frequency filtering and directional coverage in industrial, telecommunications, and broadcast sectors where reliable and interference-free operation is paramount.
