Overview
The CompleTech CA340O omnidirectional coaxial dipole antenna delivers reliable 326-353 MHz signal transmission with a 2 dBi gain and vertical polarization for industrial and telecom applications. This antenna features a copper radiator for superior conductivity and a UV-resistant ABS/FG radome with PU foam filling for weatherproof durability. The CA340O supports multiple connector options (N-, TNC-, 7/16-female) to match existing infrastructure, ensuring installation flexibility. With a VSWR of less than 1.5 and a 50-ohm impedance, it provides optimized impedance matching for reduced signal loss. The omnidirectional radiation pattern (H-plane 360° coverage, E-plane 81° beamwidth) ensures consistent coverage in all directions.
Designed for pole mounting on 35-60 mm diameter poles using an aluminum alloy bracket and stainless steel hardware, the CA340O withstands wind loads up to 55 N. Its IP67-rated enclosure protects against dust and water ingress, while the DC-short-circuited design provides lightning protection. Operating from -40°C to +80°C, this antenna is ideal for telecommunications, broadcasting, and industrial IoT deployments where dependable connectivity is critical. The antenna’s compact form factor and robust construction make it suitable for harsh environments, including outdoor installations exposed to extreme temperatures and weather conditions. The copper radiator ensures low-loss signal transmission, while the ABS/FG PU foam radome resists corrosion, UV degradation, and mechanical stress. The multiple connector compatibility allows seamless integration with various RF systems, reducing downtime during deployment. The 55 N wind load rating ensures stability in high-wind scenarios, and the IP67 rating guarantees reliable performance in dusty or wet conditions. The DC-short-circuited design enhances safety by diverting lightning-induced currents away from sensitive equipment.
