| AY-1850 | UHF High Gain Yagi Antenna | 1700-2000MHz | 13 dBI |  |  |  |
The AY-1850 is a professional-grade, high-gain directional Yagi antenna engineered for the 1700–2000 MHz L-band and upper UHF spectrum. Delivering a robust 13 dBi (11 dBd) gain, this antenna is optimized for DCS, PCS, and UMTS bands, as well as specialized 1.8 GHz telemetry and point-to-point microwave links. Its compact 0.65-meter design ensures rapid deployment and high survivability in extreme environmental conditions.
Precision Directional Focus
The AY-1850 provides sharp, directive performance with a 55-degree horizontal and 45-degree vertical beam-width. Combined with an 18 dB Front-to-Back Ratio, it allows system engineers to establish high-intensity links while effectively rejecting co-channel interference and background noise from the rear and sides.
Innovative Feed and Matching
The unique design of the AY-1850 utilizes a specialized matching feed system that acts as an internal impedance transformer. This eliminates the need for traditional folded dipoles, resulting in higher radiated efficiency and a stable VSWR of better than 1.5:1 across a wide 200 MHz bandwidth. The feed point is enclosed in a ruggedized Nylon housing, providing a hermetic seal against moisture, ice, and salt spray.
Industrial-Grade Construction
Built for permanent outdoor installation, the antenna is constructed from high-quality 6063T6 architectural aluminum alloy. The radiating elements are permanently fixed to the 19 mm support boom, ensuring that electrical alignment remains perfect even under high vibration or heavy wind loads. The antenna is factory-tuned and requires no field adjustments, providing "out-of-the-box" reliability.
