Wavelink Yagi Antennas
Wavelink Yagi antennas provide long-range, reliable communication where remote monitoring is needed. They are used in many industrial and commercial applications where a point-to-point or point-to-multipoint communication is required and where line of sight can be achieved. This is suitable for many applications, but Wavelink antennas seem to find their niche in SCADA (Supervisory Control and Data Acquisition) systems, telemetry (i.e., remote communication), and various kinds of wireless networked automation setups.
The Wavelink Yagi is a fairly rugged antenna that is specified for use in many harsh outdoor environments. Each Yagi is constructed with aluminum, a metal that is both lightweight and durable, and which, along with the antenna housing, is also very corrosion resistant. The Yagi is UV-resistant and is designed to withstand a range of harsh outdoor conditions, including fairly wide temperature ranges and very high humidity levels.
FAQs
What are Wavelink Yagi antennas used for?
Wavelink Yagi antennas are designed for long-range, directional wireless communication in industrial and commercial applications such as SCADA systems, telemetry networks, and remote monitoring.
What frequency ranges do Wavelink Yagi antennas support?

What is the typical gain of a Wavelink Yagi antenna?
Depending on the model, Wavelink Yagi antennas generally provide between 6 and 13 dBi of gain, allowing for extended coverage and improved signal clarity over long distance
Can Wavelink Yagi antennas be used in SCADA and telemetry systems?
Yes. These antennas are ideal for point-to-point or point-to-multipoint communication links in SCADA, telemetry, and process control systems used in water, wastewater, and energy applications.
Are Wavelink Yagi antennas compatible with other manufacturers’ equipment?
Yes. As long as the frequency range and connector type match, Wavelink Yagi antennas can be used with most industrial radios, modems, and wireless access points.
The Yagi-Uda Antenna
The Yagi-Uda antenna is a directional antenna that can transmit and receive data coming from a specific direction (the direction the antenna is facing). Thus, directional antennas must be aimed in the direction of the potential signal transmitter. Aiming the antenna correctly is essential for optimal reception. Knowing the width of the antenna's signal pattern is the best way to ensure optimal aim.
Advantages of Yagi-Uda antennas:
Directionality: They are highly directional and can be used to transmit or receive signals in a specific direction. This makes them ideal for long-distance communications, as they can concentrate power in a specific direction.
High gain: They have a high gain, which means that they can amplify signals and improve reception quality.
Low noise: They have a low noise level, which means that they can filter out interference and improve signal quality.
Cost-effective: They are relatively inexpensive and easy to construct, making them an affordable option for many applications.
Disadvantages of Yagi-Uda antennas:
Limited coverage area: They have a narrow beam width, which means that they have a limited coverage area. They are best suited for point-to-point communications over long distances.
Unidirectional: They are unidirectional, which means that they can only transmit or receive signals in one direction. This can be a disadvantage if the direction of the signal changes frequently.
Size: They can be large and cumbersome, making them difficult to install in certain locations.
Weather-sensitive: They can be sensitive to weather conditions, such as wind and rain, which can affect their performance.
