Horizontally Polarized Omnidirectional Antennas
- Halo The simplest form - a dipole bent into a circular shape.
- Big Wheel More elaborate. Mainly used on VHF and UHF.
Circularly Polarized Omnidirectional Antennas
- Turnstile Often used for satellite communications.
Verticallly Polarized Omnidirectional Antennas
All vertical antennas with a single element are omnidirectional radiators.
