Hi Ed, We have pushed our test capability to 3000 v/m right now, but that's only from 1 to 18 GHz. The limit is the chamber size, our chamber was built to test small boxes ( like shoe box size ). This chamber is mode tuned. We plan to make one big enough for DO-160 testing, but so far have no results to share.
For the very high fields, I would avoid the galvanized Steel panels, they lower the Q. A big problem we faced was field probes for these levels: I still haven't found what I'd call the ideal probe. We have only tested 1 box that was tested here at 200 v/m and went on for the very high fields ( 14 kV/m and higher ), it passed both places, so not a great data point I'm afraid.
