CA170C3

The CompleTech CA170C3 is a high-gain, offset-pattern collinear antenna engineered for reliable communication in the 163-177 MHz frequency band. Designed for vertical polarization, this 10 dBi antenna delivers exceptional signal propagation with a horizontal beamwidth of 179° and vertical beamwidth of 20°, ensuring broad coverage in both horizontal and vertical planes. The antenna features a VSWR of less than 1.5, indicating minimal signal reflection and efficient power transfer, while its copper radiator ensures optimal conductivity and durability. The CA170C3 is built for harsh environmental conditions, with a UV-resistant ABS/FG radome and closed-cell PU foam filling that provides IP67 protection against dust and water ingress. The radome encloses all electromechanics, safeguarding internal components from moisture, corrosion, and mechanical stress. The antenna’s lightweight design and low wind load of 165 N make it ideal for pole-mounted installations on structures with diameters ranging from 35-60 mm, using the included aluminium alloy bracket and stainless steel V-bolts. Versatile connectivity is provided via N-female and TNC-female connectors, accommodating a wide range of RF systems. The antenna includes integrated impedance compensation and an RF choke, reducing interference and ensuring stable performance across the specified frequency range. With a DC-shorted feed point, the CA170C3 offers lightning protection, safeguarding connected equipment from transient voltage spikes. Operating within a temperature range of -40°C to +80°C, this antenna is suitable for industrial monitoring, telemetry, SCADA systems, and specialized communication networks in demanding outdoor environments. Key features include field-adjustable pattern and optional beam tilting, allowing customization to specific coverage requirements. The antenna’s compact design and robust construction make it a cost-effective solution for applications requiring dependable, long-range communication in the VHF band.
