The reason I use 1/2 wavelengths of coax is because I want to see the actual antenna impedance and not just the SWR. SWR may not change along a cable length but impedance sure does and a 1/2wave of coax repeats the actual impedance and allows me to be a bit further away from the antenna while testing it. I just used some old R/S RG8x.
