Dave,
I have two of the longer SMA F-F adapters, from two similar NanaVNA kits.
I checked them on my 8753D. Both look reasonable to the 6GHz limit of my
8753D. Each shows a 900MHz through loss of about 0.07dB, and a reflection
loss of about 0.3dB. A random adapter from my lab looks slightly better,
but not much.

There is obviously quite a bit of variation among them. You and Rune find
them okay, I find it poor and Kurt even worse.

I expect George Orwell would have said, all adapters are equal, but some
are more equal than others.???

Dave.
