Overview
The CompleTech CA140B2 is a bidirectional broadside antenna engineered for reliable performance within the 135-145 MHz frequency range. This antenna features a gain of 6 dBi and vertical polarization, ensuring effective signal transmission and reception for critical communication systems. Constructed with a durable ABS/FG PU foam radome and a copper radiator, the CA140B2 is built to withstand environmental challenges, maintaining signal integrity. Its VSWR is rated at less than 1.5, minimizing signal loss due to reflection and maximizing power transfer efficiency. The antenna is equipped with N-/TNC-female connectors for secure and stable connectivity. Designed for pole mounting, it accommodates diameters from 35 mm to 60 mm, offering installation flexibility. With a substantial wind load rating of 126 N, the CA140B2 is engineered for long-term operational stability in exposed locations. This antenna is suitable for applications requiring bidirectional communication in the VHF band, such as base stations, repeaters, and point-to-point links. The CA140B2 complements other CompleTech antennas like the CA140D and CA140C2, which offer different radiation patterns and gain levels within the same frequency band.
