VNA TestBed (SMA) v1

This is a simple testbed designed to test SMA antennas with the Nano VNA. I wanted a reliable way to get a known ground plane and stable platform with known cable distance and impedance, making the Antenna under testing the largest moving variable.The center hole is ~6.4mm to accomodate the ¼" SMA threaded diameter of the Female connector.The legs are short but have a ~2.5mm hollow core for easy mounting on dowels, or to self-tap M2.5 risers (shown in the example images).Suggestions and improvements welcome!
