A circular polarity antenna sends off radio frequency in a "directional" left or right circle from the antenna. If visible, the transmission signal would look like a spring. MicroTek does not offer standard circular polarized antennas for a number of reasons. The main reason being that circular antennas are twice as susceptible to outside interference when compared to omni-directional or directional linear polarized antennas. Since a circular polarized signal path is a directional 360-degree circle, it is more susceptible to vertical and/or horizontal interference. This interference cannot be filtered out due to the circular nature of the signal. While circular polarized antennas will allow signals to be transmitted further, the tradeoff in interference may offset that advantage.
