Ideal for vehicles, temporary sites and small installations requiring improved mobile network performance.

## Long description

Portable Wittenberg Antennen LTE Antenna MIMO 4x4 (K-103527) is an external cellular antenna designed to improve LTE signal reception and transmission for routers, modems and gateways. As a 4x4 MIMO solution it supports multiple-input multiple-output configurations to enhance throughput and reliability in mobile broadband setups. The compact portable form factor makes it suitable for temporary installations, vehicles and small fixed sites where improved mobile network performance is required.
Advantages
The antenna provides four independent antenna elements arranged for MIMO 4x4 operation to increase data throughput and signal robustness in supported LTE networks. Its external placement and directional characteristics help reduce signal attenuation compared with internal antennas, improving uplink and downlink quality. The portable design allows quick deployment and repositioning without permanent installation, and compatibility with common cellular routers and modems simplifies integration into existing systems.
Suitable for
 Mobile broadband routers and gateways requiring enhanced LTE reception
 Temporary or portable sites such as events, fieldwork or pop-up offices
 Vehicles and vans where an external portable antenna is needed
 Small fixed installations with limited mounting options
When it may not be suitable
This external MIMO 4x4 antenna is intended for improving LTE cellular links; it does not replace specialised antennas for Wi‑Fi, GPS, or other radio services. If your equipment does not support MIMO or lacks compatible external antenna connectors, the full benefits of a 4x4 solution may not be realised. For large permanent installations requiring high-gain directional coverage over long distances, a dedicated high-gain mast-mounted antenna may be more appropriate.
Key specifications
 Technology: LTE cellular antenna with MIMO 4x4 capability
 Frequency coverage: cellular LTE bands (multi-band operation for mobile broadband)
 Polarisation: multiple antenna elements arranged for diversity and MIMO
 Mounting: portable external form factor suitable for temporary mounting or vehicle use
 Compatibility: designed for use with routers, modems and gateways that accept external cellular antennas
How to use
Mount the portable antenna externally where it has a clear view toward the serving cell towers, keeping it away from large metal objects that can block signals. Connect the antenna to the router or modem using the appropriate cables and connectors compatible with your device. After connecting, verify the device shows improved signal levels and, if available, enable or configure MIMO settings on your router to utilise all four antenna ports. Reposition the antenna for best reception and secure it temporarily for the duration of use.
What to consider before purchase
 Ensure your router or modem supports external antennas and has the required number and type of antenna connectors
 Confirm the antenna covers the LTE frequency bands used by your mobile network operators
 Check whether you need cables and connector adapters—these may not be included
 Decide if a portable external antenna meets your long-term mounting and environmental durability needs
Usage recommendations
Place the antenna as high as practical and orient it toward the nearest cell towers. Test different mounting positions and cable routings to reduce interference and loss. Use low-loss cables and proper connectors to maintain signal quality, and verify modem firmware and settings support MIMO operation to take full advantage of the 4x4 configuration.
