Overview
The CompleTech CA140S2 is a directional stacked Yagi array antenna engineered for reliable operation within the 135-145 MHz frequency band. This antenna delivers a significant 9 dBi gain, ensuring robust signal transmission and reception for critical communication systems. Its design supports both vertical and horizontal polarization, offering flexibility for diverse deployment scenarios. The CA140S2 features a durable construction with a copper radiator for optimal conductivity and an ABS/FG PU foam radome to withstand environmental factors. With a low VSWR of less than 1.5, signal reflection is minimized, leading to improved system efficiency and performance. Connectivity is facilitated by N- and TNC-female connectors, providing secure and standard interfaces. The antenna is designed for pole mounting on diameters ranging from 35 mm to 60 mm, allowing for straightforward installation. It is rated for a wind load of 168 N, indicating its stability in outdoor installations. The UNSPSC code for this product is 43221706. The CompleTech CA140S2 is suitable for applications requiring directional signal focusing in the VHF band, such as point-to-point communication links, telemetry, or specialized radio systems where precise signal directionality and gain are paramount. Its construction materials and specifications are aligned with the robust requirements of industrial and commercial communication infrastructure.
