Antenne sectorielle ALLNET ALL19025

The ALLNET ALL19025 sector antenna is a compact, high-gain antenna designed for operation in the 4.9–5.875 GHz frequency range. With a maximum gain of 18 dBi, vertical polarization and 50 Ω impedance, it is suited for deployment in wireless networks that require directed coverage and improved link performance. The antenna’s dimensions (215 mm × 50 mm × 200 mm) and modest weight make it convenient for mounting on poles, masts or wall brackets in outdoor or sheltered installations.

Advantages

The antenna provides focused coverage with 18 dBi gain to extend range and increase signal stability in point-to-multipoint and sectorized deployments. Vertical polarization aligns with many access points and client devices, reducing polarization mismatch. Its 50 Ω impedance ensures compatibility with common RF equipment. The compact form factor and light weight simplify installation and reduce wind load compared with larger sector antennas.

Suitable for

• Outdoor sector coverage for Wi‑Fi networks in the 4.9–5.875 GHz band
• Point-to-multipoint links where directional gain and controlled pattern are required
• Wireless ISP installations and campus connectivity to serve sectors of clients
• Replacement or upgrade of existing vertical-polarized sector antennas

How to use

Mount the sector antenna on a suitable pole, mast or wall bracket at a height and orientation that provide clear line of sight to the served area. Connect the antenna to RF equipment using appropriate low-loss coaxial cable and connectors rated for outdoor use, keeping cable runs as short as practical to minimize loss. Ensure the antenna is securely fastened and weather-sealed at cable entry points. Observe local regulations for outdoor antenna installations and grounding requirements.

Recommendations

Position the antenna to cover the intended sector with minimal obstructions and align polarization with the connected radios. Use surge protection and proper grounding for outdoor deployments, and verify connector compatibility and cable attenuation to preserve the 18 dBi performance in the link budget.
