Antennas that can transceive signals in a horizontally-polarized, omni-directional manner are described. In an example embodiment, an antenna comprises a spiraling surface having a spiral cross-section, the surface forming an internal cavity, an internal channel to the external surface, and an internal wall common to the cavity and the channel. Further, an example embodiment comprises a longitudinal opening allowing access to the cavity and the channel by a transmission feed line. Alternate embodiments comprise various cross-sectional configurations, and may also comprise a radome at least partially surrounding the antenna spiraling surface and supporting structure.
