Radiates and receives energy equally in all horizontal directions, called an omnidirectional antenna. This antenna is best suited for applications requiring full coverage. In addition, the outstanding feature of the omnidirectional antenna is its rod radome, like a monopole antenna. The terms "rubber duck" and "whip antenna" are commonly used.

Additionally, high gain omni antennas work by pushing energy lobes in from the top and bottom, and out in a doughnut-like pattern . If you keep pushing towards the ends of the pink balloon, it creates a pancake effect with a narrow vertical beamwidth but a large horizontal coverage. This high gain antenna design provides long communication distances, but has one drawback.
