Overview
The CompleTech CA150S2+ is a directional stacked yagi array engineered for reliable communication within the 144-156 MHz frequency band. This antenna delivers a substantial 11 dBi gain, ensuring robust signal reception and transmission critical for professional and industrial applications. Its design supports both vertical and horizontal polarization, offering deployment flexibility. The radiator is constructed from copper for optimal conductivity, housed within a durable ABS/FG PU foam radome that provides environmental protection. The CA150S2+ features a low VSWR of less than 1.5, minimizing signal reflection and maximizing power transfer efficiency. Mounting is facilitated on poles with a diameter ranging from 35 to 60 mm. The antenna is built to withstand significant wind loads, rated at 320 N, ensuring stability in challenging weather conditions. Connector options include N-female and TNC-female, providing broad compatibility with various radio systems. This stacked yagi array is suitable for point-to-point communication links, telemetry, and other applications requiring directional signal focusing in the VHF band. Its specifications are derived from the CA150S2+ model, emphasizing its performance characteristics for demanding operational environments.
