What made you think my flat spiral coil was acting like a waveguide at
microwave frequencies?

Your logic is at odds with my experimental results.  It is clear from the
stationary coronal discharge on the topload that longitudinal standing waves
with no current was achieved (i.e. no wasteful streamers were produced).
