Circular wave antennas for 5.8 GHz

Model No. ant13002931210-19

Circularly polarized waves are often used in satellite communications, and also have characteristics that make them less susceptible to unwanted reflection of radio waves from the surroundings (multipath).

Our circularly polarized antennas are available for both right-handed and left-handed circular polarization.

KEYCOM can provide the anttenas both of right-circular polarization / left circular polarization upon your request,please feel free to contact us.
