Outdoor 4G LTE Antenna ALFA AOA-4G-8F 8 dBi IP67 N-Female

ALFA AOA-4G-8F is an outdoor 4G LTE antenna with 8 dBi gain, housed in an IP67-rated weatherproof enclosure and fitted with an N-female connector. It is designed to improve mobile broadband reception for routers, modems and gateways by increasing signal strength and stability. The antenna is intended for fixed external mounting on walls, poles or masts to extend range and improve throughput in areas with weak cellular coverage.

Advantages

The antenna offers 8 dBi directional gain to enhance uplink and downlink performance for 4G LTE networks, while the IP67-rated housing protects electronics from rain, dust and temporary immersion. The N-female connector enables a secure, low-loss connection to compatible coaxial cables and external cellular equipment. Its compact form factor and mounting provisions simplify installation on vertical or horizontal surfaces.

Suitable for

• Improving 4G LTE signal for home or small office routers and gateways
• Fixed outdoor installations on walls, poles or masts
• Enhancing mobile broadband performance in suburban and rural areas with weak cellular coverage
• Use with cellular modems and routers that support an external N-female antenna connection

When it may not be suitable

This antenna is not intended for mobile or vehicle-mounted use where frequent movement and vibration occur; mounting and weather sealing assume a fixed installation. It is a single-band 4G LTE antenna designed for cellular frequencies and may not provide optimized performance for non-cellular bands (for example, Wi‑Fi or GPS) unless explicitly specified by the communication equipment.

Key specifications

• Frequency range: designed for 4G LTE cellular bands
• Gain: 8 dBi
• Connector type: N-female
• Ingress protection: IP67 weatherproof enclosure
• Mounting: wall, pole or mast compatible mounting hardware
• Application: outdoor fixed installations for routers, modems and gateways

How to use

Mount the antenna securely on a wall, pole or mast at a location with the clearest line of sight toward the nearest cell tower, elevated above surrounding obstructions where possible. Run a compatible low-loss coaxial cable from the N-female connector on the antenna to the external antenna port of your router, modem or gateway, using appropriate weatherproofing for cable entries. After connection, check signal strength and adjust antenna orientation or position to maximize reception and throughput. Ensure all fittings are tightened and any mounting brackets are corrosion-resistant for long-term outdoor use.

What to consider before purchase

• Confirm that your router or modem supports an external antenna with an N-female interface or that you have an adapter to the required connector type
• Verify the antenna’s frequency coverage matches the 4G LTE bands used by your mobile operator in the installation area
• Plan cable run length and choose appropriate low-loss coaxial cable to minimize signal loss over distance
• Assess mounting location for line of sight and exposure to weather; ensure compatible mounting hardware is available

Usage recommendations

For best results, place the antenna as high as practical, away from large metal objects and other antennas. Use high-quality, weather-rated cable and connectors, and verify operator band support before installation. After installation, test signal strength in different orientations to determine the optimal alignment for stable 4G LTE reception.
