the ultralog antenna r&s®hl562e is used for measuring emissions as well as for ems purposes in the broad frequency range from 30 mhz to 6000 mhz. measurement times are considerably reduced since changing antennas is not necessary.
symmetry and matching (vswr) of the r&s®hl562e allow 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 does not only increase antenna gain but is the reason for the radiation pattern in h-plane being almost rotationally symmetrical to the one for the e-plane.
the ultralog is supplied without a tripod; the tripod shown is available as an extra. for use with the r&s®hl562z1 tripod, an rf cable with a 90° angle connector is required.
