Summary

Description
English: Television antennas. These six antennas are of a type called a Yagi-Uda antenna, widely used for television reception at VHF and UHF frequencies. They consist of a series of parallel metal rods. One pair of rods, called the driven element, collects the radio waves and is attached to a cable that conducts the television signal to the television. The other rods, called parasitic elements, serve to increase the sensitivity of the antenna to signals coming from a particular direction.
