CompleTech CA85B4 bidirectional stacked broadside - Frequency range: 83-88 MHz - Gain: 9 dBi…

The CompleTech CA85B4 is a bidirectional stacked broadside antenna designed for reliable communication in the 83-88 MHz frequency range. This antenna offers a substantial 9 dBi gain, ensuring efficient signal transmission and reception for critical applications. Its vertical polarization and bidirectional pattern provide consistent coverage, making it suitable for point-to-point or distributed communication systems. The CA85B4 features a robust construction, including a UV-resistant ABS/FG radome with PU foam filling for enhanced durability and weather resistance. The radiator is constructed from high-conductivity copper, ensuring optimal signal integrity. With a VSWR of less than 1.5, this antenna minimizes signal reflection and maximizes power transfer. Connectivity is handled by versatile N-female or TNC-female connectors, offering flexibility in system integration. Mounting is facilitated by an aluminum alloy bracket compatible with poles ranging from 35 to 60 mm in diameter, secured with stainless steel V-bolts and self-locking nuts. The antenna is designed for harsh environmental conditions, boasting an IP67 rating for dust and water ingress protection and operating across a wide temperature range of -40°C to +80°C. It also features DC short-circuiting for lightning protection. The CA85B4 is engineered with frequency-independent data points, including a combination of durability, light weight, and low wind load (336 N). Additional features include a radome-enclosed radiator, all electromechanics molded inside closed-cell PU foam, a DC shorted feed point, integrated impedance compensation, and an integrated RF choke. This antenna is an ideal choice for telecommunications, broadcasting, and industrial IoT deployments requiring dependable performance and longevity. Manufacturer: CompleTech, SKU: CA85B4.
