.05 MFD.

The streamer length is of course in no way really related to the output
potential.  Our static single-shot firing will establish the correct
potential for the coil, ie, peak potential is the same.  This can also be
measured with a ball type spark gap --- we use a 7 inch dia sphere ground
gap for medium size coils and a 14 inch dia sphere ground gap for large
toroids, ie, 34 x 8.5 and 48 x 12 inch.

They seems to agree close 3-5% of planar antenna pickups with the planar
probe back a specified distance from the coil.
