Introduction This Report describes measurements of the radiation pattern characteristics of UHF television receiving antennas. The measurements were made to determine the performance of twelve UHF antennas used for TV reception. Though all antennas tested were designed for multiband operation@ the antennas tested covered@ inter alia@ the frequency range of TV channels 40 to 60 for 8 MHz channel plans and TV channels 41 to 65 for 7 MHz plans. These frequency ranges are extensively used for terrestrial television broadcasting services by most ITU administrations.
