Antena dupla 4G-LTE omnidirecional QOLTEC 57045 12 dBi

Omnidirectional 4G LTE dual antenna QOLTEC 57045 12 dBi is designed to receive and transmit cellular LTE signals evenly across all horizontal directions. With a 12 dBi gain and dual-element configuration, the antenna improves signal strength for routers, modems and outdoor installations while supporting multi-connector or MIMO setups to enhance data reliability and coverage in areas with variable reception.

Advantages

The antenna's omnidirectional radiation pattern provides consistent coverage around the installation site, reducing the need for precise aiming. A 12 dBi gain increases effective signal range and uplink/downlink performance for compatible LTE equipment. Dual elements allow for use in MIMO configurations or connection to two devices, enabling improved throughput and more stable connections. The unit is built for outdoor mounting and designed to integrate with common cellular networking hardware.

Suitable for

• Improving mobile LTE signal for home or small office routers and modems
• Outdoor installations on poles, masts or building facades
• MIMO setups to increase data throughput and connection reliability
• Remote or rural locations with weak cellular coverage

Key specifications

• Frequency range: compatible with LTE bands used for 4G networks
• Gain: 12 dBi
• Radiation pattern: omnidirectional in the horizontal plane
• Configuration: dual-element / dual-antenna setup for MIMO or separate connections
• Mounting: outdoor-capable mounting for pole or wall installation

How to use

Mount the antenna outdoors at an elevated position clear of large metal obstructions to maximize line-of-sight to nearby cell towers. Connect the antenna cables to the corresponding ports on your router or modem, following the device manufacturer's guidance for MIMO or primary/secondary antenna connections. Tighten connectors securely and route cables to avoid water ingress at connection points. After installation, verify signal improvement and adjust height or position if necessary to optimize reception.

Recommendations

For best results, place the antenna as high as practical and away from large reflective surfaces. Use weatherproof cable glands and corrosion-resistant fittings for permanent outdoor installations. When using MIMO, ensure both antenna ports are connected and configured in the router or modem settings.
