Antena dupla 4G LTE exterior QOLTEC 57047 5 dBi omnidirecional

Outdoor 4G LTE Dual Antenna QOLTEC 57047 5 dBi Omnidirectional is an external cellular antenna designed to improve 4G LTE signal reception for routers, modems and gateways. The antenna features a two-feed (dual) configuration that supports MIMO-capable devices and dual-connector installations. Its omnidirectional radiation pattern and 5 dBi gain provide balanced coverage around the mounting location, while the weather-resistant enclosure is intended for fixed mounting on poles or walls in outdoor environments.

Advantages

The dual-feed design enables simultaneous connection of two coaxial cables to support MIMO setups, which can increase connection stability and throughput in areas with moderate to weak cellular coverage. With 5 dBi omnidirectional gain, the antenna offers a compromise between range and broad-angle reception without requiring mechanical aiming. The housing is built to withstand outdoor conditions and mounting hardware allows secure installation on vertical or horizontal surfaces.

Suitable for

• Improving 4G LTE reception for home or office routers and gateways
• Supporting MIMO configurations to enhance mobile broadband throughput
• Fixed outdoor installation on poles, masts or walls
• Use in rural or urban fringe areas with variable signal strength

Key specifications

• Frequency range: compatible with standard 4G LTE bands
• Gain: 5 dBi omnidirectional
• Polarization: dual-feed, suitable for MIMO
• Mounting: pole or wall mountable housing
• Environmental protection: weather-resistant outdoor enclosure

How to use

Select a mounting location with clear exposure to the sky and minimal obstructions, such as a rooftop, pole or wall. Attach the antenna securely using the supplied mounting bracket or compatible hardware, orienting it vertically for standard omnidirectional performance. Run coaxial cables from the antenna’s two connectors to the corresponding antenna ports on your 4G LTE router, modem or gateway, ensuring proper connector types and torque. After connection, check signal strength and adjust cable routing or mounting height as needed for best reception.

Recommendations

Use low-loss coaxial cables and maintain tight, corrosion-free connections. Avoid routing cables near high-power electrical lines or large metal objects that could cause interference. If the device supports MIMO, connect each antenna feed to the designated ports to maximize throughput and connection stability.
