Flat-Patch Antenna ALLNET ANT-58-3T3R-PATCH-385

The ALLNET Flat-Patch Antenna ALLNET ANT-58-3T3R-PATCH-385 is a compact directional antenna designed for 5 GHz wireless networks. It operates across the 5.15–5.85 GHz frequency range, offers a maximum gain of 15 dBi and supports dual polarization to improve signal quality. The antenna uses a 50 Ω impedance and an N-type connector, with a low VSWR of 2:1 and a maximum power handling of 10 W. Its flat-patch form factor and dimensions of 385 mm × 80 mm × 385 mm make it suitable for installations where a low-profile directional antenna is required.

Advantages

The antenna provides high directional gain up to 15 dBi while maintaining a compact, low-profile design that fits indoor and outdoor mounting locations. Dual polarization helps to maintain stable links in environments with varying signal orientations, and the N-type connector ensures reliable RF connections. Low VSWR (2:1) and 50 Ω impedance contribute to efficient power transfer and reduced reflections, while the 10 W maximum power rating accommodates typical access point and radio transmitter power levels.

Suitable for

• Point-to-point and point-to-multipoint Wi‑Fi links in the 5.15–5.85 GHz band
• Directional coverage for access points and wireless bridges
• Indoor or sheltered outdoor installations requiring a low-profile antenna
• Environments where dual polarization improves connection robustness

How to use

Mount the antenna pointing toward the target coverage area, ensuring a clear line of sight when possible for optimal directional performance. Connect the N-type connector to a compatible 50 Ω radio or cable assembly, and verify connectors are tightened to manufacturer torque recommendations. Align polarization with the corresponding radio equipment or use the dual-polarization capability to match the remote device orientation. After installation, test the link using RSSI, throughput, and VSWR measurements and adjust aiming or height to achieve the desired signal quality.

Recommendations

For best results, install the antenna where it has minimal obstructions and away from large metallic surfaces that can affect radiation patterns. Use appropriate weatherproofing for outdoor cable connections and confirm that the connected radio’s transmit power does not exceed the antenna’s 10 W rating. Regularly inspect mounting hardware and connectors to maintain reliable performance.
