CompleTech CA400N4 cardioid pattern notch - Frequency range: 380-410 MHz - Gain: 8 dBi - Polarization…

The CompleTech CA400N4 is a specialized cardioid pattern notch antenna engineered for precise frequency control within the 380-410 MHz band. This antenna delivers a consistent 8 dBi gain, ensuring robust signal transmission and reception in demanding industrial environments. Its vertical polarization is optimized for specific communication setups, while the low VSWR of less than 1.5 guarantees excellent signal integrity and minimal reflection. The radiator is constructed from durable copper, and the radome is made from UV-resistant ABS/FG with PU foam filling, providing protection against environmental factors and ensuring longevity. Designed for secure mounting, the CA400N4 accommodates poles with a diameter of 35-60 mm using an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. The antenna features DC short-circuiting for lightning protection and operates reliably across a wide temperature range of -40°C to +80°C. Its IP67 rated construction signifies complete protection against dust and immersion in water, making it suitable for harsh outdoor installations. The CA400N4 is equipped with both N-female and TNC-female connectors for versatile connectivity. With a wind load rating of 136 N, this antenna is built to withstand significant wind forces, ensuring stable performance. Key features include a field-adjustable pattern and optional beam tilting capabilities, further enhancing its adaptability. The integrated impedance compensation and RF choke contribute to its overall performance efficiency.
