HF AntennasR&S®HFH2-Z6E Active Rod Antenna
50 Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog 2017/2018
The R&S®HFH2-Z6E active rod antenna measures the elec-
trical field strength in the LF, MF and HF frequency range.
It can be used for EMI measurements in line with various
standards (i.e. CISPR, MIL, FCC, ANSI, ETSI).
Each antenna is individually calibrated.
It is characterized by an almost frequency-independent
antenna factor and very high sensitivity.
In strong field environments, an attenuator can be activat-
ed to reduce distortion. An integrated RF detector with a
threshold circuit reports overload of the antenna.
The antenna is supplied via a coaxial cable using the op-
tional R&S®IN600 bias unit.
