## Summary description

QOLTEC 57015 is an omnidirectional 4G LTE DUAL antenna with 7 dBi gain designed for both indoor and outdoor use. It provides omnidirectional reception and transmission for cellular 4G LTE signals, supports dual-feed configurations, and is suitable for improving mobile data reception, routers and signal boosters in homes, offices and remote sites.

## Long description

QOLTEC 57015 is an omnidirectional 4G LTE DUAL antenna with 7 dBi gain designed for both indoor and outdoor installation. It offers uniform reception and transmission in all horizontal directions, optimising cellular signal coverage for mobile devices, routers and repeaters. The antenna supports dual-feed operation to work with devices that require two antenna connections for diversity or MIMO performance, and its robust design makes it suitable for residential, commercial and remote deployments.
Advantages
The antenna provides a moderate 7 dBi gain that improves signal strength without creating a narrow beam, ensuring stable omnidirectional coverage around the installation point. Dual-feed capability allows use with modems and routers that rely on two inputs for enhanced throughput and connection stability. Its indoor/outdoor rating enables flexible placement options — wall-, mast- or window-mounted installations are possible depending on signal needs and surroundings. The product is compact and engineered for reliable operation across standard 4G LTE frequency bands.
Suitable for
 Improving mobile data reception for smartphones and tablets in weak-signal areas
 Connecting to 4G LTE routers and gateways to increase cellular throughput and stability
 Use with signal boosters and repeaters to extend coverage in homes or small offices
 Remote or rural sites where omnidirectional coverage is preferred over directional aiming
Key specifications
 Polarisation: omnidirectional horizontal plane coverage
 Gain: 7 dBi
 Frequency coverage: standard 4G LTE bands (multi-band cellular operation)
 Configuration: dual-feed (two antenna ports for diversity/MIMO)
 Installation: suitable for indoor and outdoor mounting (wall, mast or window)
 Construction: weather-resistant housing for outdoor use
How to use
Select a mounting location with the clearest line of sight and minimal obstructions for best omnidirectional performance. Mount the antenna on a stable surface, using a mast, wall bracket or window mount as appropriate, and route the supplied or compatible coaxial cables to your 4G router, modem or signal booster. Connect each feed to the corresponding antenna input on the device, ensuring secure and weatherproofed cable connections for outdoor installations. After installation, check signal levels and adjust placement or height if necessary to optimise reception and throughput.
Usage recommendations
For optimal results, place the antenna as high as practical and clear of large metal objects or dense obstructions. Use high-quality, low-loss coaxial cable and proper outdoor-rated connectors when installing outdoors. If your equipment supports MIMO or diversity, connect both feeds to the corresponding ports to benefit from improved data rates and reliability.
