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.

0.250 Semi-Rigid |
0.250" Semi-Rigid coaxial cable provides mode free operation to 19 GHz. The sold tin-plated copper tube effectively provides 100% RF shielding with shielding effectiveness exceeding 110 dB, and enables the dielectric and center conductor to remain precisely spaced. This results in optimum impedance ... |
19 GHz | 0.23 dB/m |

0.250 Semi-Flex |
0.250" Semi-Flexible coaxial cable is a formable, microwave grade with mode free operation to 19 GHz. The tin-soaked copper braid provides near 100% RF shielding and the malleable nature of the outer jacket eliminates solder joint failures and allows bends immediately behind the fillet. Standard 0 ... |
