Main Features
The LX-1721-1.5S-ANT is engineered for high-mobility environments requiring a secure yet temporary mounting solution. With a 400MHz bandwidth, it covers the essential 1.7GHz to 2.1GHz LTE spectrum, ensuring compatibility with 4G and 3G networks globally. The antenna stands at 109mm, featuring a vertical polarization architecture that maintains stable signal links during movement. Its strong Ø30mm magnetic base allows for instant attachment to metal surfaces, such as vehicle roofs or industrial enclosures, without the need for permanent drilling. The integrated 1500mm RG174 low-loss cable provides the flexibility needed for interior routing while maintaining a 50 Ohm impedance for optimal power transfer.
Application Scenarios
- Vehicle Telematics & Fleet Management: Temporary or permanent roof-mount cellular connectivity for trucks, vans, and service vehicles.
- M2M & Industrial IoT: External antenna solution for smart meters, vending machines, and remote monitoring enclosures.
- Signal Testing & Field Surveys: Quick-deploy antenna for cellular site surveys and signal strength drive testing.
- Emergency Communication Kits: Easily storable and deployable antenna for mobile command centers and portable LTE gateways.

Product Q&A
- How does the magnetic base impact the antenna’s performance?
- The magnetic base serves two purposes: it provides a secure physical mount and, when attached to a metal surface, the surface acts as a “ground plane.” This ground plane reflects RF energy and helps the antenna achieve its specified 3dBi gain and radiation pattern stability.
- Is the 1.5-meter cable length customizable?
- While the standard model comes with a 1500mm RG174 cable, the assembly can be customized for specific project requirements regarding cable length and connector types (such as TNC or N-Type) to match your cellular gateway or router.
- Can this antenna withstand high-speed vehicle movement?
- Yes. The Ø30mm high-strength magnetic base is designed to remain secure under normal driving conditions. For extreme vibration or high-wind environments, ensure the mounting surface is clean and flat to maximize magnetic adhesion and structural integrity.
