VHAP - VHF Precision Half-Wave Dipole

Field strength measurements in the VHF-UHF range are usually based on half-wave dipoles, which have the same directional diagram at all frequencies when adjusted to 0.45 l to 0.5 l; this is important because of the considerable influence of earth reflection - the frequency-dependent diagram of all broadband antennas allows different effects of earth and surroundings to be effective. 

On the other hand, broadband antennas offer great advantages in automated measurement. Often there is therefore the task of calibrating a broadband antenna by means of high-precision dipoles on a specific measuring section. 

Furthermore, there is a requirement to check the suitability of a measuring section in such a way that measured and calculated values of the dipole antenna section, attenuation is compared. The results can either be used to determine the suitability of the measuring section or corrections can be determined which allows good measuring accuracy even in less suitable terrain (see also CISPR 16 Appendix G).
