The low loss half-wave dipole UHA 9125 D has a usable frequency range from 1 GHz to 4 GHz. Depending on the desired center frequency, dipole elements with the corresponding length are supplied. The moveable shorting bar is set to a quarter wavelength to provide a good symmetry.

Application:

Half-wave dipoles are often used to generate defined radiated power. The dipole is fed with RF-power, leading to the same field strength reading, as created by the EuT before. (EuT is substituted by a dipole) The required RF-power at the dipole's N-connector is determined, representing the ERP-value (Effective Radiated Power). To obtain the EIRP-value (Effective Isotropic Radiated Power), the RF-power has to be increased by 2.15 dB, because an ideal half wave dipole has an isotropic gain of 2.15 dBi.

 Specifications:     

 Insertion of an attenuator is advisable if the equipment presents a high internal SWR (e.g. in the 0 dB position of an internal step attenuator. In this case the attenuation must be added to the antenna factor (dB/m) or subtracted from the gain (dBi, dBd).
