Log-periodic antenna
log-periodic antennas most be used at ultra-short wave frequency band, they can also be used as short-wave communication antenna and Medium wave, short wave broadcast transmission antenna. It has a high efficiency with an almost expected transmission value and better directivity, easy site construction and easy maintenance compared with other high gain antennas.
