Antenna QuWireless Qoltec 4G LTE magnetic base 5 dBi omnidirectional indoor 600–2700 MHz SMA 3 m cable

The QuWireless Qoltec 4G LTE magnetic base antenna is an omnidirectional indoor antenna designed to improve cellular signal reception across a broad frequency range. With a 5 dBi gain and coverage from 600 to 2700 MHz, this antenna supports 4G LTE and other cellular bands used by routers, modems and signal boosters. It comes with an integrated 3 m cable and an SMA connector for straightforward installation and compatibility with many consumer and professional devices. The magnetic base allows temporary or semi-permanent mounting on metal surfaces, offering a simple way to position the antenna for better reception in homes, offices or vehicles.

Advantages

The antenna offers omnidirectional reception, reducing the need for precise orientation and enabling more consistent coverage within indoor spaces. Its 5 dBi gain provides a balance between range and pattern stability suitable for urban and suburban environments. The magnetic base enables quick placement on metal surfaces without drilling, while the 3 m cable gives flexibility in locating the antenna for optimal signal. The SMA connector ensures broad compatibility with many routers, modems and cellular boosters that accept external antennas.

Suitable for

• Improving 4G LTE signal for home and small office routers
• Enhancing modem or mobile hotspot reception in buildings
• Temporary mounting on vehicle roofs or metal surfaces for travel
• Use with cellular signal boosters and repeaters that accept SMA antennas

Key specifications

• Type: Omnidirectional indoor antenna
• Frequency range: 600–2700 MHz
• Gain: 5 dBi
• Connector: SMA
• Cable length: 3 m
• Mounting: Magnetic base for metal surfaces

How to use

Attach the SMA connector to the compatible external antenna port of your router, modem, mobile hotspot or booster. Place the antenna on a stable metal surface using the magnetic base, or use a nearby metal plate if a direct metal surface is not available. Run the 3 m cable to position the antenna where signal strength is highest, such as near a window or higher elevation within the room. Adjust the antenna location and check signal indicators on your device to find the best reception point. For vehicle use, place the antenna on a clean, flat metal area and ensure the cable routing does not interfere with door seals or moving parts.

Usage recommendations

For optimal performance, position the antenna away from large metal enclosures and electronic equipment that may cause interference. Test several locations and orientations where the magnetic base can attach, and secure cable routing to avoid damage. Verify connector compatibility and tighten the SMA connection by hand; avoid excessive force. If you require outdoor mounting or higher gain for long-range reception, consider a purpose-built outdoor antenna or a professional installation.
