English: VHF Yagi television antenna from 1954, model Super Katy-1, manufactured by Kay-Townes Antenna Co., Rome, Georgia. This is an example of the complicated Yagi antenna designs that were developed to cover the US analog television frequencies, which were split between two bands; channels 2 - 6, 47 - 88 MHz, and channels 7 - 13, 174 - 240 MHz. In general, the shorter elements functioned as half-wave dipoles for the higher frequency band, the longer straight ones functioned on the lower band, and the slanted elements functioned both on the low band and, at their second harmonic, on the higher band. The beam direction of the antenna is to top right. The design of these early TV antennas is described in Edward M. Noll & Matthew Mandl, The Continuous Evolution of Television Antennas, p. 64 in the source. Alterations to image: cloned out advertising copy in background.
