That is not the point here ... whether the antenna is an electric or
magnetic radiator, it *will* interact with items in the near field.
*Further* the cobweb is an electric radiator just like any other
dipole or yagi and will interact with its environment in the same
way as any other *reduced size* antenna.
Again, the folding may result in some field cancellation in the
immediate environment but that is nothing more than a symptom of
*reduced efficiency* just like *any other reduced size antenna.*
