CompleTech CA140C3 offset pattern collinear - Frequency range: 135-145 MHz - Gain: 10 dBi - Polarization…

The CompleTech CA140C3 is a high-gain offset pattern collinear antenna engineered for reliable VHF communication in the 135-145 MHz frequency range. Designed for industrial, telecom, and broadcast applications, this antenna delivers a 10 dBi gain with vertical polarization, ensuring strong signal transmission and reception over long distances. The copper radiator and UV-resistant ABS/FG PU foam radome provide exceptional durability and weather resistance, while the DC-short circuited feed point and integrated RF choke enhance lightning protection and signal integrity. Key specifications include a low VSWR of less than 1.5, ensuring minimal signal reflection and maximum efficiency. The antenna supports flexible mounting on poles with diameters between 35-60 mm using an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. With a robust wind load rating of 189 N, the CA140C3 is built to withstand harsh environmental conditions, including temperatures from -40°C to +80°C. The IP67-rated construction ensures protection against dust and water ingress, making it ideal for outdoor installations. The CA140C3 features a field-adjustable pattern and optional beam tilting, allowing for optimized coverage in specific deployment scenarios. The N-/TNC-female connector ensures secure and stable connectivity, compatible with a wide range of radio equipment. Whether used for point-to-point communication, wireless networks, or broadcast systems, the CA140C3 provides superior performance, durability, and reliability in demanding environments.
