CompleTech CA340C3 offset pattern collinear - Frequency range: 326-353 MHz - Gain: 10 dBi - Polarization…

The CompleTech CA340C3 is an offset pattern collinear antenna operating within the 326-353 MHz frequency range. This antenna delivers a gain of 10 dBi with vertical polarization, ensuring robust signal transmission and reception for critical communication systems. Its design features a triangular feed and offers field-adjustable patterns with optional beam tilting capabilities, providing flexibility in deployment. The CA340C3 is constructed with a UV-resistant ABS/FG radome filled with PU foam, offering excellent durability and environmental protection. The radiator is made of copper for optimal conductivity. The antenna is designed for secure mounting on poles with a diameter of 35-60 mm, utilizing an aluminum alloy bracket with stainless steel V-bolts and self-locking nuts. This robust attachment method ensures stability even under challenging conditions. Key specifications include a VSWR of less than 1.5, minimizing signal reflection and maximizing efficiency. The connector type is N-female / TNC-female, providing versatile connectivity options. The antenna is rated IP67, indicating complete protection against dust and immersion in water up to 1 meter. It operates reliably within a temperature range of -40ºC to +80ºC. The lightning protection is DC-short circuited, enhancing safety and system longevity. With a wind load rating of 108 N, the CA340C3 is built to withstand significant environmental stresses. This antenna is suitable for applications requiring reliable communication in the 326-353 MHz band, including private networks, public safety communications, and industrial IoT deployments. Its combination of durability, precise radiation patterns, and weather resistance makes it a dependable choice for demanding environments. The frequency-independent data highlights its construction benefits: durability, lightweight design, low wind load, IP67 proof construction, and a DC-shorted feed point with integrated impedance compensation and RF choke.
