L-240

L-240, sometimes referred to as LMR-240, is a low loss coaxial cable with a medium sized 6.10 mm outer diameter. This series is without a doubt the most popular choice of RF cable, due to its efficient compromise between performance and cost. 

L-240 cable provides the flexibility and easy installation of a smaller diameter cable, with the low attenuation and shielding advantages of a larger cable. Unlike larger cables, L-240 can pass 5G and mmWave frequencies up to 31 GHz.

The cable is a mid-size with an overall diameter of 6.10 mm, providing a compromise between form-factor/bend radius, and attenuation/power handling. The double shielded outer conductor provides exceptional RF shielding exceeding 90 dB, and PE jacket for a service life in excess of 20 years.

Terminating L-240 coaxial connectors requires a 6.48 mm (.255") hex die.
