The reason for height-scanning is that there are unavoidable reflections from
the groundplane, and the only way to ensure that your measurement geometry is
not causing a deep null is to scan the height. The reason that reflections
are unavoidable is that at 30MHz, absorber would have to be 2.5m

Hello,
I have a need to make radiated measurements up to 40 GHz. I uses a low loss
cable that gives me enough dynamic range up to 18GHz. The cable is very
