R&SHL562 ULTRALOG
30 MHz to 3 GHz Ultra-broadband antenna for EMI and EMS applications
Features
JJ Only
one antenna required to cover an extremely wide frequency range JJ Selectable polarization plane JJ Gain increase at high frequencies JJ Generation of high field strengths for EMS measurements JJ Compact size JJ Individual calibration in line with ANSIC63.5 Brief description The R&SHL562 ULTRALOG combines the characteristics of a biconical and a log-periodic antenna. The ULTRALOG is mainly used for measuring emissions in the extremely wide frequency range from 30MHz to 3 GHz without change of the antenna. The log-periodic part of the antenna is V-shaped in order to increase system sensitivity in particular between 500MHz and 1 GHz. Unlike conventional solutions, this gain-increasing measure allows the compact size of the ULTRALOG to be maintained. Optimized symmetry and matching (VSWR) of the ULTRALOG allow its use in EMS measurements where field strengths of 10V/m or higher are required. The ULTRALOG is supplied without tripod; the tripod shown is available as an extra. For use with the R&SHL562Z1 tripod, an RF cable with a 90° angle connector is required.
