CA140D

The CompleTech CA140D is a high-efficiency offset pattern dipole antenna engineered for reliable communication in the 135-145 MHz frequency range. Designed for industrial, military, and telecommunications applications, this antenna delivers a 5 dBi gain with a low VSWR of less than 1.5, ensuring optimal signal transmission and reception. The CA140D supports both vertical and horizontal polarization, providing deployment flexibility in diverse environments. Constructed with a copper radiator and protected by a durable ABS/FG PU foam radome, the antenna is built to withstand demanding conditions. The radome offers UV resistance and IP67-rated protection, safeguarding internal components from moisture, dust, and environmental stress. The antenna’s lightweight design minimizes wind load (63 N), making it suitable for pole mounting on diameters ranging from 35-60 mm using an aluminum alloy bracket and stainless steel V-bolts. The CA140D is compatible with multiple connector types, including N-, TNC-, and 7/16-female, ensuring seamless integration with existing RF systems. Its operating temperature range of -40°C to +80°C and DC-short circuited feed point enhance reliability in extreme conditions. The integrated RF choke and impedance compensation further improve performance, reducing interference and optimizing signal integrity. Ideal for applications requiring robust, high-gain antennas, the CA140D is a versatile solution for VHF communication systems, including land mobile radio, public safety networks, and industrial telemetry. Its field-proven design and compliance with UNSPSC 43221706 make it a trusted choice for mission-critical installations.
