Antena exterior 4G LTE QOLTEC 57020 14 dBi — antena direcional para banda larga móvel

Directional outdoor 4G LTE antenna QOLTEC 57020 with 14 dBi gain is a weather-resistant external antenna designed to improve mobile broadband reception for routers and modems. The antenna focuses cellular signals in a chosen direction to increase receive and transmit performance in areas with weak coverage. It includes mounting hardware for installation on poles or walls and is intended for permanent exterior placement to support more reliable voice and data connections.

Advantages

The antenna provides a high directional gain of 14 dBi to extend range and strengthen signal quality toward a specific cell tower. Its robust, weatherproof housing and corrosion-resistant mounting bracket allow sustained outdoor use in varied climates. Designed for compatibility with common mobile routers and modems, the unit helps reduce packet loss and improve throughput by concentrating the antenna pattern in a targeted direction. The included hardware simplifies alignment and mounting on poles or walls.

Suitable for

• Improving 4G LTE reception in rural and remote locations
• Boosting signal for home or small office mobile broadband routers
• Stabilizing connections for voice-over-LTE and data services in weak-signal areas
• Outdoor hotspot installations and temporary field sites

Key specifications

• Frequency range: compatible with common 4G LTE bands (cellular frequencies)
• Gain: 14 dBi directional
• Polarization: linear (directional)
• Housing: weather-resistant, suitable for outdoor use
• Mounting: includes pole and wall mount hardware
• Connector type: compatible with standard mobile broadband coax connectors (verify router/modem port type before purchase)
• Operating environment: designed for outdoor temperature and humidity ranges

How to use

Mount the antenna on a pole or wall using the supplied bracket and fasteners. Point the antenna toward the nearest or strongest cell tower for the best directional reception; use a signal meter or the router's signal indicators to fine-tune alignment. Connect the antenna cable to the external antenna port on your router or modem, ensuring the connector matches the device. After mounting and connection, verify improved reception and adjust angle or position if necessary to optimize throughput and stability.

Recommendations

For reliable results, install the antenna as high as practical and clear of large obstructions such as trees or buildings. Check compatibility of the antenna connector with your router or modem and, if required, use an appropriate low-loss coaxial cable and adapter to minimize signal loss. Periodically inspect mounting hardware and seals to maintain weatherproofing and performance.
