As I’ve mentioned before, connecting the series cap from the antenna post to ground forms an “L” network that works FB for loading into an end-fed half wave wire antenna.
Voltage rating of the cap more of a consideration here than in the series connection but have found the gray, cylindrical Russian caps to work FB in this configuration as well.
