Factory Capabilities

Core Design: Solid Bare Copper (BC) inner conductor paired with Foam Polyethylene (PE) insulation ensures effective signal transmission, achieving an impressive 80% Velocity of Propagation.

Advanced Production Lines:

Shielding: Bonded aluminium tape and tinned copper braid provide 90dB shielding effectiveness, maintaining signal integrity in high-interference environments.

Frequency Coverage:

OEM:

 Operating up to 6GHz, the LMR-200 supports a wide range of RF applications, including VHF, UHF, and microwave frequencies. Its design ensures minimal signal loss and robust performance across the spectrum.

We offer OEM manufacturer service, which means custom-made cables.
There is an increasing need for cable to be customised to meet a customers specific requirements.
Such as changing the colour of a sheath on a standard cable, to composite cables with different sized cores, with various levels of screening. Also we can use inner conductor with different materials including copper, Tinned copper, CCS, CCA and TCCA to match the costs and performance.
In addition, cables can be over-sheathed in PE, PVC or LSZH materials to satisfy different requirements. In the case of PVC, we can also stripe outer sheaths to provide easy identification.

FAQ

Why choose LMR-400?

LMR-400 is an extremely popular coaxial cable in the industry due to its excellent reliability, unsurpassed flexibility and ultra low attenuation. The LMR-400 cable has loss figures comparable to the extremely rigid corrugated coaxial cables however manages to achieve similar flexibility to that of high loss RG Cables. LMR-400 is around 40% lower attenuation than RG-8, RG 213, RG 214 and 9913 Air-Dielectric type Cables.

How is the LMR-400 low loss figures achieved?

This is achieved due to the cable construction specifications. The centre conductor uses a high conductivity, solid bare copper clad covered aluminium centre conductor material. The dielectric is nitrogen injected, foamed, closed cell, Polyethylene which helps achieve 84% Velocity of Propagation. The Dielectric has a Aluminium foil outer conductor, which is chemically bonded on to it. Due to the cable construction, The attenuation is significantly lower as compared to single shielded coaxial cables: RF shielding of LMR-400 is > 90 dB as compared to 40 dB for RG8.
