The First Candelabra for Circularly Polarized Broadcast Antennas

A study of a circularly polarized (CP) television multiple antenna installation shows that improved measurement and theoretical techniques are required to model the scattered horizontal pattern circularity and video response in a candelabra. Previously developed guidelines for horizontally polarized antennas in a candelabra are inadequate to describe the expected performance of CP antennas in the same configuration. Results of calculations and measurements of model CP antennas for a Columbus, Ohio candelabra are included.
