The RFI YBA818-82 is a vertically polarized, dual-bay 18-element Yagi array designed for 19 dBi high-gain directional communication across the 850-930 MHz frequency range. Built for RF control and long-haul point-to-multipoint applications, this antenna features rugged construction, excellent intermodulation performance, and the flexibility to be upgraded to a 4-bay array for even greater gain.

Product Features:

• The antenna is configured as a dual-bay Yagi array, delivering 19 dBi gain for high-performance vertical polarization communication.
• It operates across the 850-930 MHz frequency range, making it ideal for RF control and telemetry systems.
• Both feed elements are fully folded dipoles welded to the boom, ensuring maximum bandwidth, low intermodulation, and high reliability.
• Passive elements are through-mounted and welded on both sides to a circular boom, minimizing corrosion and intermodulation effects.
• The all-welded construction ensures long-term durability and consistent performance in harsh conditions.
• The alodined finish provides a conductive surface for effective grounding and corrosion resistance.
• The antenna is suitable for vertically polarized installations only.
• It can be upgraded to a 4-bay array using the PA84-82 stacking kit, which includes spacing control frames, fiberglass supports, and a two-way phasing harness.

Application Areas:

• The antenna is ideal for vertically polarized point-to-point RF control systems.
• It is suitable for long-haul point-to-multipoint communication links.
• It is a reliable solution for installations requiring high gain and minimal interference.
• The design supports scalable deployments with optional 4-bay configuration for enhanced performance.
