This document has been composed to provide a industry reference for the major coaxial cable groups and their nominal specifications. Cable grouping is important to ensure compatibility across different manufacturers. Rather than introduce a brand new cable type with unique dimensions, RF cable manufacturers typically produce their cable to align with a well known cable group. This ensures connectors from one company can be used on another company's cable.

This can sound confusing, so to help illustrate the point consider the following example. Powertec produce coaxial cables such as our PTL-240, which sits alongside others including CommScope CNT-240, Telegärtner G30, Times Microwave LMR-240, and many others, who all manufacture an "L-240" group cable.

LMR300 coaxial cable layers

L-300

L-300 is a 50 Ω mid-size coaxial cable with an overall diameter of 7.62 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 ...

RG8 coaxial cable layers

RG-8

RG-8 is a type of RF coaxial cable commonly used in VHF/UHF applications such as ham radio or CB radio installations. It is characterised by its large diameter, good shielding and power handling, and low signal loss over distance, making it ideal for long-range transmissions. However, its size can ...
