Show me a non-directional antenna.

Omnidirectional antennas attempt to radiate equally horizontally. An isotropic antenna radiates equally in all directions but is only theoretical. All antennas have some gain.

Just because you call it non-directional doesn't mean it is. They all have gain compared to a theoretical isotropic antenna.
