CompleTech CA140S3 directional stacked yagi array - Frequency range: 135-145 MHz - Gain: 10 dBi…

The CompleTech CA140S3 is a directional stacked yagi array specifically engineered for operation within the 135-145 MHz frequency range. This antenna is designed to deliver a significant gain of 10 dBi, which translates to enhanced signal strength and improved performance in point-to-point communication systems. The construction of the CA140S3 incorporates a robust copper radiator, chosen for its excellent conductivity and durability. Protecting the internal components is a radome constructed from ABS and FG PU foam, providing resilience against environmental factors encountered in outdoor and industrial settings. A key feature of the CA140S3 is its support for both vertical and horizontal polarization. This dual-polarization capability offers significant flexibility, allowing users to adapt the antenna to a wide variety of operational requirements and signal propagation conditions. Signal integrity is further assured by a very low VSWR (Voltage Standing Wave Ratio) of less than 1.5. This specification is critical as it minimizes signal reflection back towards the transmitter, thereby maximizing the efficiency of signal transmission and reception. For connectivity, the CA140S3 is equipped with N-/TNC-female connectors, ensuring a secure and reliable interface for coaxial cable connections. Installation of the antenna is facilitated by a mounting system designed to accommodate poles with a diameter ranging from 35 mm to 60 mm, allowing for straightforward integration onto standard masts and support structures. The antenna's structural integrity is further underscored by its rating for a wind load of 252 N, indicating its capability to withstand significant wind forces and maintain stable operation even in challenging weather conditions. These specifications collectively position the CA140S3 as a durable and high-performing solution for demanding communication applications.
