High gain 27dBi directional parabolic antenna GL1742V-27

Product Introduction

1. High Gain for Long - Range Signals: The GL1742V - 27 offers an impressive gain of 27dBi. This high gain allows the antenna to effectively capture and transmit signals over long distances. Whether it's for point - to - point communication between remote locations or for receiving weak signals in areas with poor coverage, the antenna's high - gain performance ensures reliable connectivity.

2. Wide Frequency Range: Operating in the 1710 - 4200MHz frequency range, the GL1742V - 27 is suitable for a variety of applications. This wide - band coverage makes it compatible with different wireless systems, such as some microwave communication links, certain satellite - based communication setups, and specific industrial wireless applications that operate within this frequency spectrum.

3. Vertical Polarization and Good Directivity: With vertical polarization and relatively narrow beam widths (16° horizontally and 12° vertically), the GL1742V - 27 has excellent directivity. The vertical polarization can be advantageous in specific environments, reducing interference from horizontally polarized signals. The narrow beam widths help in focusing the signal in a particular direction, which is beneficial for minimizing interference from other sources and maximizing the signal strength in the desired area.

4. Stable Electrical Characteristics: It has a VSWR of ≤2.0 and an input impedance of 50Ω. The low VSWR ensures efficient power transfer from the source to the antenna, minimizing signal reflection. The 50Ω impedance is a standard value that enables easy integration with a wide range of wireless devices and systems, providing a stable and reliable electrical connection.

5. Durable Construction: The reflector of the GL1742V - 27 is made of aluminum, which is not only lightweight but also highly durable. It can withstand the forces of wind, with a rated wind velocity of 60 m/s. The white - colored reflecting surface helps in reflecting signals effectively, and the antenna can operate in a temperature range of - 40°C to + 65 °C. This durability makes it suitable for both indoor and outdoor applications, even in harsh environmental conditions.
