Outdoor antenna ALFA AOA-4G-5F — 4G/LTE outdoor antenna, 5 dBi gain, IP67, female connector

The ALFA AOA-4G-5F is an outdoor 4G/LTE antenna designed to improve mobile broadband reception for routers and modems. Housed in an IP67-rated weatherproof enclosure, it provides a stable 5 dBi gain and uses a female F-type connector for straightforward attachment to compatible equipment. This antenna is intended for fixed outdoor mounting to increase signal strength and consistency in home, vehicle, or remote-site deployments where cellular connectivity requires reinforcement.

Advantages

The antenna’s 5 dBi gain offers a moderate increase in signal reception without creating a highly directional beam, making it suitable for general-purpose outdoor coverage. Its IP67-rated casing protects against dust and temporary immersion, enabling installation in exposed environments. The female F-type connector simplifies connection to many outdoor routers and signal amplifiers, while the compact form factor allows discreet mounting on walls, poles or roofs.

Suitable for

• Improving 4G/LTE signal reception for home or small office routers
• Fixed outdoor installation on roofs, walls or poles
• Enhancing mobile broadband in remote or suburban locations
• Use with routers, modems and amplifiers featuring an F-type female/male interface

When it may not be suitable

This antenna provides a moderate 5 dBi gain and is not intended for long-range, highly directional reception or professional cellular base-station applications. It may be insufficient where extreme signal amplification or multi-band MIMO arrays are required. Additionally, compatibility depends on connector type and router/modem antenna input; adapters may be necessary for systems using different connector standards.

Key specifications

• Frequency: 4G/LTE bands (cellular frequencies compatible with standard 4G/LTE deployments)
• Gain: 5 dBi
• Ingress protection: IP67 (dust-tight and protected against temporary immersion)
• Connector type: female F-type
• Mounting: outdoor fixed mount (wall, pole, roof)
• Operating environment: outdoor use, resistant to weather exposure

How to use

Mount the antenna outdoors in a location with clear access to the sky and minimal obstructions, such as on a roof, pole or exterior wall. Secure the housing using appropriate brackets or clamps and orient the antenna to maximize signal strength toward the nearest cell tower when known. Connect the female F-type connector to the corresponding cable or adapter that leads to your router or modem. After installation, verify signal levels on your device and adjust position or orientation if needed to achieve optimal reception.

What to consider before purchase

• Confirm that your router or modem accepts a female F-type connection or whether an adapter is required.
• Check which 4G/LTE frequency bands are used by your mobile provider and ensure compatibility.
• Consider mounting location, cable length, and weather exposure to plan installation and cabling needs.

Usage recommendations

Position the antenna as high as practical with a clear line of sight toward the cell tower, use quality low-loss coaxial cable, and minimize connector adapters to preserve signal. For best results, test a few mounting positions and verify reception improvements before permanently fixing the mount.
