It doesn't mean much. RG stands for "radio guide" and the numbers
are purely arbitrary (there isn't 174 of anything in RG-174). While
each number name tells you some things, such as the maximum voltage,
characteristic impedance, and a rough idea of its physical size, it
never was a full specification. So depending on the cable, two
cables with the same RG number can have completely different shields,
different dielectrics, different jackets, etc.
As opposed to RF, digital audio, guitar and microphone cables, which
all have a number of unique requirements, the panel connections in a
synth module is a very undemanding application. It's a relatively
large low-bandwidth signal over a very short distance. As you might
have noticed, some modules don't even use coaxial cables.
