Introduction
LMR® cable is a low-loss, flexible coaxial cable intended for high-frequency RF signal transmission. LMR cables were developed as a sophisticated alternative to classic coaxial cables such as RG58 or RG213, and they are widely used in telecommunications, Wi-Fi, cellular, GPS, and antenna systems. They provide superior shielding, minimal signal attenuation, and longevity in outdoor or industrial settings.
At Eteily Technologies, we offer high-quality LMR cables and unique cable assemblies designed for optimal RF performance in global markets.
Understanding the LMR® Cable Structure :
- Inner Conductor: Made of bare or tinned copper for high conductivity.
- Dielectric: Foam polyethylene (PE) to reduce signal loss.
- To guarantee good isolation, dual shielding is used, consisting of bonded aluminum foil and tinned copper braid.
- Jacket: UV-resistant polyethylene for outdoor and waterproof performance.
Features of the LMR® Cable :
- Low signal loss: Up to 30% less loss than typical RG cables.
- UV and weather resistant: suitable for exterior installations.
- Superior shielding: The dual-layer foil and braid prevent EMI and RFI.
- Flexible and Simple to Install: Can be readily routed through tight places.
- Wide Frequency Range: Depending on the kind, it can operate up to 6 GHz.
- High power handling: Ideal for transmitting and receiving antenna systems.
Types of LMR® Cables :
1. LMR-100 :
- A small and flexible cable suitable for short RF connections to Wi-Fi routers, IoT antennae, and GPS modules.
2. LMR-195 :
- Provides mild loss and flexibility. Suitable for medium-length RF connections in M2M devices, vehicle-mounted antennas, and wireless access points.
3. LMR-200 :
- Low signal loss meets high flexibility; often utilized in cellular repeaters, GSM antennas, and IoT gateways.
4. LMR-240 :
- Used for long-distance RF transmission requiring somewhat better power handling and reduced attenuation – ideal for outdoor antenna expansions.
5. LMR-400 :
- A popular option for high-power RF and 4G/5G base stations. It has very low loss and great shielding, making it ideal for lengthy cable runs of up to 100 feet.
6. LMR-600 :
- Heavy-duty cable for professional applications such as military communications, broadcast towers, and high-frequency industrial equipment.
