CompleTech CA150C2 offset pattern collinear - Frequency range: 144-156 MHz - Gain: 8 dBi - Polarization…

The CompleTech CA150C2 is a high-gain offset pattern collinear antenna engineered for reliable communication in the 144-156 MHz VHF band. With an 8 dBi gain and vertical polarization, it delivers strong signal transmission and reception, making it ideal for industrial, commercial, and public safety applications such as land mobile radio, SCADA systems, and emergency communications. The antenna features a triangular feed design with field-adjustable patterns and optional beam tilting for optimized coverage in challenging environments. Key specifications include a 50-ohm impedance, VSWR <1.5, and a frequency-independent radiation pattern with a horizontal beamwidth of 181° and vertical beamwidth of 27°. The copper radiator is enclosed in a UV-resistant ABS/FG radome with PU foam filling, providing IP67-rated weatherproofing and corrosion resistance. The compact design mounts on poles with diameters between 35-60 mm using an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. Electrical robustness includes a DC-shorted feed point, integrated impedance compensation, and RF choke for lightning protection. The antenna operates reliably across -40°C to +80°C and withstands wind loads up to 120 N. Connectivity is via N-/TNC-female connectors, ensuring compatibility with standard coaxial cables. The CA150C2 is part of CompleTech’s offset pattern collinear series, known for durability, low wind load, and field-proven performance in critical communication systems.
