This detailed product description introduces a high-performance 1650–1800 MHz 14 dBi Yagi Antenna. Engineered for the crucial mid-band frequency spectrum, this antenna is designed to provide maximum signal capture and transmission for specialized, licensed communication systems, cellular repeater setups, and dedicated data links. The Yagi's distinctive array structure provides a substantial 14 dBi directional gain, making it the superior choice for establishing stable, long-distance, and high-integrity wireless connections where signal stability and range are the primary objectives.
Key Technical Attributes and Performance
The Yagi antenna, known for its focused power and rugged design, is specifically tuned to operate with high efficiency across a vital mid-band frequency window.
Targeted Mid-Band Frequency Coverage (1650–1800 MHz)
The antenna is precisely optimized for the 1650 MHz to 1800MHz range. This spectrum is highly relevant globally, encompassing or sitting adjacent to key cellular and dedicated licensed communication bands:
Cellular Capacity Bands: This range is near the DCS/LTE Band 3 (1800 MHz) and the AWS Band 4 (1700 MHz), making the antenna ideal for applications requiring focused, high-gain access to these critical cellular capacity layers, often for donor antennas in repeater systems.
Specialized Wireless Links: The band is also utilized for various dedicated, high-data-rate communication links, where its balance of range and available bandwidth is highly advantageous over lower or higher frequencies.
Superior Range-to-Capacity Ratio: The frequency offers better propagation characteristics (less path loss) than 2.4GHz or 5 GHz, allowing the 14 dBi gain to push the signal reliably over significantly longer distances.
High 14 dBi Gain via Yagi-Uda Array
The Yagi-Uda design is renowned for achieving extremely high gain through a focused structure of passive director and reflector elements surrounding an active driven element.
Maximum Directional Power: The 14 dBi gain is highly concentrated into a very narrow, intense directional beam. This tight focus is crucial for establishing reliable Point-to-Point (PTP) links over long distances, compensating for atmospheric and geographical signal attenuation.
Interference Suppression: The directional nature provides exceptional rejection of noise, static, and interference originating from outside the primary beam path (high Front-to-Back Ratio). This isolation dramatically improves the Signal-to-Noise Ratio (SNR), which is essential for ensuring high-quality voice and data communication with minimal error.
Clean Uplink/Downlink: The focused pattern ensures that power is used efficiently and directed solely toward the target receiver or transmitter, minimizing wasted energy and potential interference to other systems.
Rugged, All-Weather Construction
The Yagi antenna is constructed to endure continuous, long-term exposure in the harshest outdoor environments:
Durable Materials: Typically constructed from corrosion-resistant aluminum or stainless steel elements mounted on a robust boom. This ensures mechanical integrity against extreme temperatures, high winds, and icing.
Weatherproof Junction: The feed point (where the coaxial cable connects to the active element) is sealed within a durable, waterproof junction box, protecting the sensitive connection from moisture ingress and ensuring low-loss electrical performance.
Fixed Mounting: The design facilitates secure, permanent mounting on towers, masts, or building facades, often including fine-tune adjustment mechanisms for precise aiming.
Usage Scenarios: Long-Distance and Dedicated Communications
The extreme gain and directional nature of the 1650–1800 MHz Yagi antenna make it an indispensable component for focused, high-reliability wireless infrastructure.
Cellular Repeater and Signal Booster Systems (Donor Antenna)
This is a critical application. The antenna is used as the donor antenna in high-power cellular repeater or signal booster setups:
Remote Tower Acquisition: Installed at a site with poor native cellular coverage, the Yagi is precisely aimed at a distant commercial cellular tower operating in the 1700 MHz (Band 4) or 1800MHz (Band 3) range. The 14 dBi gain pulls in a weak, usable signal, which is then fed to the repeater system for amplification and local redistribution. This is vital for maintaining service in deep rural areas or large industrial buildings.
Point-to-Point (PTP) Data Links
Two identical Yagi antennas are aligned to create a dedicated, high-gain wireless data bridge:
Extended Backhaul: Establishing reliable data links for backhauling information between geographically separated corporate or municipal buildings over many kilometers. The Yagi's focus ensures link integrity even at the maximum possible distance for the frequency band.
Remote Sensing: Providing a stable command and data link to remote infrastructure assets, such as specialized monitoring stations, weather buoys, or remote power generators.
Professional Mobile Radio (PMR) and Specialized Telemetry
For licensed professional radio services that use this mid-band spectrum, the antenna ensures clear, long-distance communication:
Dispatch and Command: Used at fixed dispatch locations to maintain reliable voice and data contact with mobile units operating over a wide service area.
Utility SCADA Systems: Providing a high-integrity link to control and data acquisition (SCADA) units for monitoring critical infrastructure where reliable signal penetration and distance are key requirements.
Fringe-Area Fixed Wireless Access (FWA)
In rural FWA deployments operating in dedicated mid-band licensed spectrum, the Yagi can be installed at the remote customer premises to target a distant WISP base station, ensuring the customer receives the high-speed data service even from the extreme edge of the network's coverage cell.
The 1650–1800 MHz 14 dBi Yagi Antenna provides the necessary robust gain and directional control to conquer distance and noise, making it the definitive choice for establishing critical, high-reliability wireless links in the demanding mid-band spectrum.
