Outdoor Omni Antenna ALFA AOA-4G-5W-NM — 4G LTE 5 dBi, N male, wall-mount

ALFA AOA-4G-5W-NM is an outdoor omni-directional antenna engineered for 4G LTE networks. With a compact wall-mount form and an N-type male connector, it is intended for permanent external installation to improve cellular reception for routers, modems and gateways in homes, offices and remote locations where a stronger mobile signal is required.

Advantages

The antenna offers a 5 dBi omni-directional gain that increases signal strength uniformly from all horizontal directions, simplifying installation because pointing is not required. Its weather-resistant enclosure and wall-mounting hardware allow stable mounting on vertical surfaces, while the N male connector provides compatibility with many outdoor cellular devices and extension cables for flexible placement. The design focuses on reception improvement for 4G LTE bands commonly used by mobile operators.

Suitable for

• Strengthening 4G LTE signal for home routers and gateway devices.
• Outdoor mounting on walls of houses, small offices or utility buildings.
• Use with cellular modems in remote or weak-signal areas.
• Integration with outdoor extension cables and N-type connectors to position the antenna away from the device.

When it may not be suitable

This antenna is omni-directional and provides modest gain (5 dBi); it is not intended for long-distance point-to-point links or situations that require highly focused directional performance. It is designed specifically for 4G LTE reception and therefore may not provide optimal performance for frequencies outside typical cellular bands or for attempting to cover very large areas by a single antenna.

Key specifications

• Frequency range: designed for 4G LTE bands (cellular frequency coverage).
• Gain: 5 dBi omni-directional.
• Connector type: N male output.
• Mounting: wall-mount bracket for vertical installation.
• Housing: weather-resistant outdoor enclosure.

How to use

Mount the antenna on an exterior vertical surface using the supplied wall bracket, choosing a location with a clear line of sight toward nearby cell towers where possible. Connect the N male connector to a compatible cable or directly to the external antenna input of a router, modem or gateway, ensuring tight and weatherproofed connections. Route the coaxial cable into the building using an appropriate cable gland or entry point and secure the cable to prevent strain. After installation, check signal levels on the connected device and adjust placement along the wall to find the best average reception; because the antenna is omni-directional, small adjustments in height and horizontal position often produce improvements.

What to consider before purchase

• Confirm your router or modem accepts an external antenna and supports an N-type male connection (or acquire a compatible adapter or pigtail).
• Verify the antenna covers the specific 4G LTE bands used by your mobile operator in your area.
• Plan the mounting location for line of sight, cable routing, and weather protection of the connector.
• Assess whether omni-directional 5 dBi gain is sufficient or a directional antenna with higher gain is required for your site.

Usage recommendations

For best results position the antenna as high as practical on an exterior wall, away from large metal objects and other antennas. Use a short, high-quality low-loss coaxial cable between the antenna and the device when possible, and seal outdoor connections with appropriate weatherproofing tape or boot to maintain signal quality and prevent moisture ingress.
