| AY-1450 | UHF High Gain Yagi Antenna | 1300-1600MHz | 13 dBi. |  |  |  |
The AY-1450 is a professional-grade, high-gain directional Yagi antenna specifically engineered for the 1300–1600 MHz L-band frequency range. Delivering a robust 13 dBi (11 dBd) gain, this antenna is optimized for long-distance point-to-point links, GPS/GNSS augmentation, and specialized telemetry. Its ruggedized, pre-assembled construction ensures rapid deployment and high survivability in extreme environmental conditions.
Precision Directional Focus
The AY-1450 provides sharp, directive performance with a 56-degree horizontal and 42-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 Efficiency
The unique design of the AY-1450 utilizes a specialized matching feed system that acts as an internal impedance transformer. This eliminates the need for traditional folded dipoles, which can be inefficient at L-band frequencies. The results are a stable VSWR of better than 1.5:1 across a wide 120 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 25.4 mm support boom, ensuring that electrical alignment remains perfect even under high vibration or heavy wind loads. The antenna is factory-tuned for any specific 120 MHz segment within its band and requires no field adjustments.
