Introduction to 18dbi Sector Antenna

This 18dbi sector antenna is engineered to meet the demands of modern communication systems and is an exceptional blend of power, precision, and reliability. This 18dbi sector antenna has a wide frequency range from 5150MHz to 5850MHz, so it ensure the seamless communication across a wide spectrum and provide you you with the flexibility and adaptability you need to thrive in diverse networking environments.

The 18dbi sector antenna also has a precised beam control ability. The 18dbi sector antenna's 65° horizontal and 7° vertical beamwidths (3dB) provide precise control over signal directionality, ensuring that your connectivity is focused exactly where you need it. This precision is especially valuable in crowded or challenging RF environments.

Built to withstand the elements, our 18dbi sector antenna boasts a robust construction. The DC Ground lightning protection further safeguards your investment, ensuring that your network remains operational even in adverse weather conditions.

Operating flawlessly at temperatures ranging from -40℃ to +60℃, and capable of withstanding wind speeds of up to 140 km/h, this antenna is designed to deliver consistent performance, even in challenging environments.

How Far Will 18dbi Sector Antenna Reach?

The reach of an 18dBi sector antenna can vary based on several factors including the transmit power of the connected device, the environment, obstacles, and the quality of the receiving equipment.

What is The Purpose of A Sector Antenna?

The sector antenna acts as a part of a base station. The sector antenna is engineered to provide coverage in a specific sector or pie-shaped region rather than in all directions like an omni-directional antenna. For example, the 18dbi sector antenna is used for 5.1/5.3/5.4/5.8 GHz Wireless LAN systems.

Does Bigger Antenna Mean Better Signal?

In general, the larger the surface area of the antenna, the more channels it's likely to receive. However, the size of an antenna is just one of many factors that can influence the performance of a wireless communication system, and it does not directly correlate with a better signal in all cases.
