SMA for the 24GHz, open, thru and short. I also have high end adaptors to N, APC, etc.

There may even be an old type N cal kit from "back in the eighties"

Those should surely be accurate enough, but what kind of connectors?

Can HP microwave loads be used? I have a set good to 24 GHz and another to
50 GHz.

My only concern with the VNWA is in its ability to measure Topband
antenna systems where sweeps are required into the AMBC band.

I'm a VERY happy owner of the 3E model VNWA. I've made measurements on my
160M antennas with no difficulty, but I'm out in the boonies, not close
enough to strong BC signals to have seen any issues.

As to precision of calibration loads -- after I got the VNWA, I did a
search looking for calibration loads, and quickly learned that if you want

better than 1% precision, it's easy to spend as much for the load as for
the VNWA itself!
