The R&S®HL562E ULTRALOG is used for emission and EMS measurements in the broad frequency range from 30 MHz to 6000 MHz Measurement times are consider- ably reduced since it is not necessary to change antennas. Symmetry and matching (VSWR) of the R&S®HL562E al- low its use in EMS measurements where field strengths of 10 V/m or higher are required. The R&S®HL562E combines the characteristics of a biconical and a log-periodic antenna. The log-periodic part of the antenna is V-shaped in order to increase the system sensitivity, in particular above 1 GHz. This measure not only increases antenna gain, it is also the reason why the radiation pattern in the H plane is practically rotationally symmetrical to the pattern in the E plane. The ULTRALOG is supplied without a tripod; the tri- pod shown is available as an extra. For use with the R&S®HL562Z1 tripod, an RF cable with a 90° angle connector is required.
