An omni-directional horizontally polarized antenna system is provided that can include an omni-directional vertically polarized antenna and a plurality of linear polarization filters concentrically surrounding the omni-directional vertically polarized antenna. The omni-directional vertically polarized antenna can generate a vertically polarized field, and the plurality of linear polarization filters can progressively rotate the vertically polarized field 90° to form a horizontally polarized field outside of the plurality of linear polarization filters.
