## Long description

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

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.
