I know that, if i want define VNA residual directivity error i should use airline ended with matched load or mismatch load (0.1 to 0.2 VRC)

I just thought, that can i use old HP 85028A directivity kit's sliding mismatch to define my residual directivity. Actualy i can get with it very nice and stable ripple above 2GHz to 18GHz.
