CA340B4

The CompleTech CA340B4 is a versatile bidirectional stacked broadside antenna designed for reliable communication across a 326-353 MHz frequency range. Engineered for adaptability, it offers field-adjustable patterns and optional beam tilting, allowing for precise signal directionality. This antenna features a robust construction with a copper radiator and a UV-resistant ABS/FG radome filled with PU foam, ensuring durability and protection against environmental factors. Its IP67 proof construction guarantees operation in harsh conditions. The CA340B4 delivers a significant 9 dBi gain, supporting efficient signal transmission and reception. It supports both vertical and horizontal polarization, providing flexibility for various deployment scenarios. Connectivity is handled via N-female or TNC-female connectors, ensuring broad compatibility. A low VSWR of less than 1.5 guarantees efficient power transfer with minimal reflection. 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 for secure attachment. Lightning protection is provided through a DC-short circuited feed point. Operating within a temperature range of -40ºC to +80ºC, the CA340B4 is built for demanding industrial and telecommunications applications. Key features include a radome-enclosed radiator, integrated impedance compensation, and an integrated RF choke for optimal performance. The combination of durability, light weight, and low wind load makes the CA340B4 a dependable choice for critical communication infrastructure.
