High-Power Transmit Directional Antennas
In the fast-paced world of communication and connectivity, the demand for robust and high-performance antennas is greater than ever. Alaris Antennas stands at the forefront, delivering great solutions of high-power directional antennas. Let's delve into the features of Alaris Antennas' offerings, particularly the LPDA, SPRL, and HELI types.
LPDA – Log-Periodic Dipole Arrays: Power, Precision, and Wide Bandwidth
Alaris Antennas' LPDA series is engineered for excellence for Electronic Attack and Counter-UAS applications. Offering linear polarization in horizontal (H), vertical (V), or both H & V configurations, these log-periodic dipole arrays provide a wide bandwidth and medium to high gain. What sets them apart is their big power rating, supporting up to a few kW at low frequencies. This makes them ideal for applications requiring high power and precision, ensuring reliable performance even in the most demanding scenarios.
SPRL – Conical Spirals for Circular Polarization: Versatility and Power
For applications requiring circular polarization, Alaris Antennas' SPRL series is the right one. Featuring conical spirals, these antennas offer medium gain, wide bandwidth, and a power rating ranging from 50 to 100W (with the HELI-A005 supporting an impressive 700W at 400-450MHz). The elongated conical shape and one or two ports add versatility to these antennas, making them adaptable to various jamming needs.
HELI – Helical Spiral Antennas: Precision in High-Gain Communication
Alaris Antennas' HELI series brings high-gain precision to the forefront for Counter-UAS applications. With a specific frequency ranges and power rating ranging from 100 to 150W, these helical spiral antennas are designed for applications where precision is needed. The elongated cylindrical shape and one or two ports enhance their suitability for specific communication requirements.
