Rohde & Schwarz HZ-13 Precision Halfwave Dipole Set, 30 MHz to 1000 MHz

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 Î© 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.
