External 4G/5G LTE Antenna QOLTEC 9 dBi, N female connector, 3 m cable

External 4G/5G LTE Antenna QOLTEC 9 dBi with an N female connector and a 3 m cable is an outdoor directional antenna designed to improve mobile broadband reception for 4G and 5G LTE equipment. The compact housing and weather-resistant construction make it suitable for wall or mast mounting, enabling enhanced signal strength and more stable data connections for routers, modems and gateways in areas with marginal coverage.

Advantages

The antenna offers a 9 dBi gain which increases uplink and downlink sensitivity, helping to extend effective range and reduce dropped connections. A fixed N female connector provides a secure, low-loss interface to cables and adapters commonly used with LTE routers and modems. The included 3 m cable simplifies installation by allowing flexible placement away from the device while maintaining a reliable signal path. The housing is designed for outdoor exposure to reduce performance loss from weather conditions.

Suitable for

• Improving 4G/5G LTE signal reception for home or small office routers
• Enhancing connectivity for outdoor or remote installations with weak coverage
• Use with gateways, modems and routers that accept N female connections via appropriate cabling or adapters
• Fixed installations on walls, poles or masts where a directional outdoor antenna is required

Key specifications

• Frequency range compatible with 4G and 5G LTE bands
• Gain: 9 dBi
• Connector type: N female
• Cable length: 3 m
• Mounting: wall or mast mountable housing
• Housing: weather-resistant enclosure suitable for outdoor use

How to use

Mount the antenna outdoors in a location with the clearest line of sight toward the nearest base station, using the supplied brackets or compatible mounting hardware. Connect the antenna to the router, modem or gateway using the integrated 3 m cable and, if necessary, an adapter to match the device input. After installation, adjust the antenna direction for the best reception and test data throughput. Secure all connections and seal any exposed cable entry points to prevent moisture ingress.

Usage recommendations

Place the antenna as high as practical and away from large metal obstructions. For best results, test multiple orientations and use signal monitoring tools available in the router or a mobile signal meter to identify the optimal alignment. Ensure connectors are tightened and weatherproofed to maintain long-term performance.
