1. @Roger do you have a photo of your S21 jig?
Attached is a photo of one I made for doing S21 measurements. It is made using one of the sections of the NanoVNA RF Test Boards that you can find on eBay, Amazon and AliExpress. Works OK for testing things like crystals, RF chokes etc. At higher frequencies the use of the edelay port extension feature will move the S11 reference plane closer to the DUT pins
