While you might get away with using your cable, good screening/****elding 
becomes increasing im****tant at the lower frequencies, as the 
interfering signals (on the outside of the coax) penetrate more easily 
through the outer ****eld. Well-screened audio would be better. In many 
cases, 'flimsy' screening may be adequate at UHF (and the cable may have 
low loss) but, again, well-screened cable will be better for preventing 
interference. Maybe it's a case of try it and see what happens?
