CA140GP

The CompleTech CA140GP is a rugged omnidirectional ground plane antenna engineered for reliable VHF communication in the 135-145 MHz frequency range. Built with a durable copper radiator and protected by a UV-resistant FG PU foam radome, this antenna delivers consistent 2 dBi gain with vertical polarization for optimal signal transmission. The N-/TNC-female connector ensures secure connectivity, while the low VSWR (<1.5) minimizes signal reflection for improved efficiency. Designed for industrial, military, and telecommunications applications, the CA140GP withstands wind loads up to 49 N and mounts securely to 35-60 mm diameter poles using an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. The antenna operates across a temperature range of -40°C to +80°C and features IP67-rated construction for protection against dust and water ingress. Its DC-short-circuited feed point provides lightning protection, ensuring long-term reliability in harsh environments.
