That is a myth. If the cable is an electrical odd multiple of 1/4-wavelength, it will fool an SWR meter into reading erroneously low because of the phase relationship between the outgoing signal and the reflected signal. If you cut your cable unnecessarily long to get an erroneously low SWR reading, you are masking antenna problems and throwing signal away, and it's not surprising you're getting poor antenna performance.
