Description
Set of UHF Precision Halfwave Dipole set 300-1000 MHz
Very good condition.
Set also known as Rohde & Schwarz HZ13.
Only used for exhibitions.
Antenna calibration, critical cases of field-strength measurement and the testing of antenna-calibration and field-strength measurement sites require special measures for establishing test standards. At both the balanced and unbalanced sides of the balun, Dipoles R&S®HZ--12 and R&S®HZ-13 contain attenuators which ensure broadband stabilization of the matching and define the total power attenuation between the dipoles and the 50 Ω termination.
As a consequence, a pair of dipoles coupled head to head will always have an exactly calibrated attenuation.
Dipole Sets R&S®HZ--12 and R&S®HZ-13 provide high precision for:
antenna calibration
field-strength measurement and
site attenuation measurement
Halfwave dipoles are especially important in the VHF/UHF range because they show the same radiation pattern at all frequencies. This is due to the fact that the dipoles are tuned to 0.5 λ and have characteristics which can be defined exactly if the elements are sufficiently thin.
