External 4G LTE antenna QOLTEC 5 dBi 600–2700 MHz SMA connector 3 m cable

QOLTEC external 4G LTE antenna with 5 dBi gain is designed to extend and stabilise mobile data reception across a wide frequency range of 600–2700 MHz. Fitted with an SMA connector and a fixed 3 m cable, the antenna supports common LTE bands and other cellular frequencies within the stated range, making it suitable for connection to routers, modems and gateways. The compact design allows for installation in homes, offices or vehicles where improved signal strength and throughput are required.

Advantages

The antenna provides a moderate directional gain of 5 dBi to increase received signal level without requiring large external hardware. Its frequency coverage from 600 to 2700 MHz makes it compatible with most 4G LTE deployments as well as several 3G and narrowband cellular signals in that range. The included 3 m cable and standard SMA connector simplify installation and allow flexible placement relative to the connected device to find the best reception point.

Suitable for (tasks / use cases)

• Enhancing 4G/LTE signal for home broadband routers and fixed wireless access devices
• Improving mobile modem and gateway reception in small offices
• Boosting cellular signal in vehicles, caravans or temporary sites with external mounting
• Stabilising data connection for IoT gateways and remote monitoring equipment operating within 600–2700 MHz

Key specifications

• Frequency range: 600–2700 MHz
• Gain: 5 dBi
• Connector type: SMA (male or adapter as required)
• Cable length: 3 m (fixed)
• Polarisation: linear (vertical)
• Suitable mounting: desktop or external surface mount

How to use

Connect the antenna's SMA connector to the compatible antenna port on your router, modem or gateway. Route the 3 m cable to place the antenna at a location with the best reception—near a window or on an exterior surface if possible. Adjust the antenna orientation to maximise signal level, then verify improved reception and throughput using the device's signal indicators or network diagnostics. If required, use an SMA adapter to match the device connector type before connecting.

Usage recommendations

For optimal performance, mount the antenna as high as practical and avoid obstructions such as metal surfaces or dense walls. When installing on a vehicle or external surface, ensure the cable and connector are protected from moisture and mechanical stress. If signal issues persist, test different placement points and orientations or consider combining this antenna with a diversity configuration if your router supports multiple antenna inputs.
