Dear Ken,
I am thinking you are missing something (hope that I am correct).
If you simply shorten the cable to zero, the problem of the missmatch, and

I have used Miteq or Mini-Circuits preamps with a custom box (Al project

sufficient at 3 or 1 meter for most frequencies between 1 - 18 GHz. The
exact model that we used has been discontinued though and I am unsure if
