Antena direcional exterior 5G LTE QOLTEC 57022 — 14 dBi, 700–3800 MHz, 50 Ω, caixa em cobre

Outdoor directional 5G LTE antenna QOLTEC 57022 — 14 dBi, 700–3800 MHz, 50 Ω, copper housing is a weather-resistant, high-gain directional antenna designed to improve cellular signal reception and transmission for outdoor installations. It supports a wide frequency range covering common 4G and 5G bands from 700 to 3800 MHz and features a white copper housing that provides mechanical durability and corrosion resistance for long-term outdoor use. The antenna presents 50 Ω impedance and up to 14 dBi maximum gain, making it compatible with standard cellular routers, modems and M2M devices that require a directional external antenna.

Advantages

The QOLTEC 57022 offers high directional gain of up to 14 dBi within a broad 700–3800 MHz frequency range, supporting multiple cellular bands in a single unit. Its copper housing delivers robust physical protection and stable performance in outdoor conditions while the white finish blends with typical outdoor enclosures. With a 50 Ω impedance and 50 W power handling, the antenna integrates easily into common telecom and IoT installations, providing improved signal strength and link reliability for devices that support an external antenna connection.

How to use

Mount the antenna outdoors on a mast or wall bracket with clear line of sight toward the desired cell tower or remote endpoint. Connect the antenna to your router, modem or radio using an appropriate 50 Ω coaxial cable and matching connectors; ensure connectors are properly sealed for outdoor exposure. Adjust the antenna orientation to maximise signal strength and lock the mounting hardware securely. Verify device compatibility with a 50 Ω antenna input and observe safe grounding practices during installation.

Recommendations

For best results, place the antenna at an elevated position and aim it toward the nearest or strongest cell site. Use low-loss coaxial cable rated for outdoor use and, where possible, add lightning protection and a grounding system. Regularly inspect mounting hardware and cable seals to maintain long-term outdoor performance.
