I doubt the cabeling matters and RG-58 would probably suffice.

You can get RG174 and other cable by th foot. e.g. https://www.showmecables.com/bulk-rg...-26-awg-per-ft

The center conductor on RG174 is flimsy, RG-58 or RG-59 are somewhat more
mechanically robust (but the insulation will have to be replaced, or spliced to a few inches
of more flexible wire). For any non-RF work, microphone cable (shielded pair) might
also be useful.
