    When performing system return loss sweeps, you will typically find that low loss, larger diameter cable will generally sweep worse for return loss than high loss, narrow diameter coax since the high loss cable absorbs more of the reflected signal. The result is a smaller amplitude reflection received at the test equipment. Long cable runs will sweep better than short rooftop applications.
