VHF/UHF Antennas R&S®HL562 ULTRALOG R&S®HL562 ULTRALOG 30 MHz to 3 GHz Ultra-broadband antenna for EMI and EMS ­applications The R&S®HL562 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 30 MHz to 3 GHz with a single antenna. The log-periodic part of the antenna is V-shaped in ­order to increase system sensitivity, in particular between 500 MHz 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 10 V/m or higher are required. 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. Key facts ❙❙ Only one antenna required to cover an extremely wide frequency range ❙❙ Selectable polarization plane ❙❙ Gain increase at high frequencies ❙❙ Generation of high field strengths for EMS ­measurements ❙❙ Compact size ❙❙ Individual calibration in line with ANSI C63.5 Rohde arz HF – VHF/UHF – SHF Antennas | Catalog 2012/2013 VHF/UHF Antennas R&S®HL562 ULTRALOG 10 kHz 1.5 10 100 MHz 26.5 10 18 1 1.3 GHz 40 1 Specifications Frequency range 30 MHz to 3 GHz Connector N female Polarization linear MTBF > 200 000 h Polarization decoupling > 20 dB Class of application laboratory Input impedance 50 Ω Operating temperature range 0 °C to +40 °C VSWR typ. < 2 Dimensions (W × H × L) Gain above 200 MHz typ. 8 dBi approx. 0.6 m × 1.65 m × 1.68 m (23.6 in × 65 in × 66.1 in) Weight approx. 5 kg (11 lb) Max. input power (TA = +40 °C) 30 MHz 150 W + 100 % AM 80 MHz 300 W + 100 % AM 250 MHz 500 W + 100 % AM 1 GHz 280 W + 100 % AM 3 GHz 180 W + 100 % AM 4 5 6 Ordering information Type Order No. ULTRALOG R&S®HL562 4041.3000.02 R&S®HL562Z1 4041.3900.02 Recommended extras Tripod, movable 7 Typical radiation patterns E plane H plane 8 30 MHz 0° 330° 1.0 30° 0.8 300° 9 60° 0.6 0.4 0.2 270° 90° 10 240° 120° 210° Typical antenna factor 0° 35 330° 30 Antenna factor in dB/m 11 150° 180° 1.0 3000 MHz 30° 12 0.8 25 300° 60° 0.6 0.4 20 0.2 15 270° 90° 10 5 240° 120° 0 30 100 1000 Frequency in MHz 3000 210° 150° 180° Rohde arz HF – VHF/UHF – SHF Antennas | Catalog 2012/2013 13
