CA150S4

The CompleTech CA150S4 is a high-gain directional stacked Yagi array engineered for the 144-156 MHz VHF band. This antenna delivers a 12 dBi gain, providing strong signal reception and transmission for reliable point-to-point and point-to-multipoint communication in industrial, commercial, and public safety applications. The CA150S4 supports both vertical and horizontal polarization, enabling flexible deployment in diverse operational environments. Constructed with copper radiators and housed in a durable ABS/FG PU foam radome, the antenna ensures long-term resistance to environmental stress, including UV exposure and moisture. The low VSWR of less than 1.5 minimizes signal reflection, optimizing power transfer and reducing system losses. With a wind load rating of 320 N, the CA150S4 maintains stability in high-wind conditions, making it suitable for outdoor installations on poles with diameters between 35-60 mm. The antenna features N-/TNC-female connectors for compatibility with a wide range of RF equipment, including radios, repeaters, and base stations. Its compact and robust design simplifies installation and maintenance, reducing total cost of ownership. Ideal for applications such as land mobile radio, amateur radio, and temporary event communications, the CA150S4 is a dependable choice for mission-critical communication systems.
