Low Loss cables

 

What is an LMR cable?

The LMR cable is a highly reliable low-loss (or Low Loss) coaxial cable used to transport high-frequency electrical signals that has two concentric conductors, a central one, called the core, responsible for carrying information, and an outer one, tubular in appearance. , called mesh, shield or braid, which serves as a ground reference and current return.

Cable type designations

We frequently receive numerous inquiries asking for different designations for this type of cable.

Commercial designations marked according to the manufacturer or supplier, but that respond to the same technical characteristics of the cable.

For example, with the LMR400 cable, perhaps one of the best known and used on the market, we also find the following names: PLMR, LMR, RG8, HDF400, CNT400, CFD400 , etc.

Construction and Design

Between the two there is a dielectric insulating layer, the quality of the cable will mainly depend on its characteristics.
Finally, the entire assembly is usually protected by an insulating cover (also called an outer jacket).

LMR cable types

Consult our wide availability of cables in stock, with different options both for sheath (PE, LSZH) and for the presentation of the cables themselves (in more manageable 100-meter rolls, or in larger-meter spools).

Applications

This 50 ohm coaxial cable, indicated for land mobile radio installations, has numerous applications:

> WIFI, GSM, 3G, 4G and LTE Systems
> Local Multipoint Distribution System (LMDS)
> Multi-Channel Multi-point Service Distribution (MMDS)
> Wireless Local Loop (SE), Personal Communication System (PCS)
> Mobile , in the creation of wireless and fixed networks.

Advantages and benefits

Among the advantages of LMR coaxial cable is a high electrical performance comparable to corrugated copper products, but with more flexibility, thus being able to help minimize costs and facilitate installation.

With the vast growth in the broadband wireless market, LMR cable is one of the best options for installations that need maximum performance and quality installation and guarantee.

Likewise, the LMR cable is really suitable for the interconnection between equipment and antennas, as well as for the construction of wireless patch cords and jumpers, thanks to its more than proven flexibility, which allows it to be channeled through narrow places without problem.

This cable has a great added value, because apart from the easy installation and handling by the assembler, it offers a quick installation and assembly.

Cover Options

The option with the black polyethylene PVC or PE cover makes the cable hard and resistant to any extreme weather situation.

Additionally, flame retardant cables (LSZH) can be supplied, which have a more sophisticated fire behavior than PE.

Connectors for this type of cable

Highly versatile, LMR cables accept a whole range of top-quality coaxial connectors, of which we also have the option of immediate supply.

Summarizing…

LMR cables offer numerous advantages and great benefits:

  • Flexibility . LMR cable can be easily routed through tight spaces without problem. The bonded tape outer conductor of the cable has sufficient flexibility and ease of bending compared to conventional corrugated copper RF cables.
  • Lost casualties . LMR cable has very low loss compared to any cable in its category. This is accomplished by using a high velocity gas injected foam dielectric and adhered aluminum tape as the outer conductor.
  • resistance . The UV black polyethylene PE sheath makes the cable hard and resistant to any extreme weather situation.
  • RF screen . Foil tape outer conductor provides 100% coverage.
  • compatibility . Compatible with all brands and manufacturers of connectors and jumpers in its category.
