Notes
For typical values of \(k_p\), \(k_h\), and \(k_v\) see ITU-R Rec F.1336-4 Sections 3.1.1.1-3.
For cases involving sectoral antennas with \(\varphi_\mathrm{3dB} \lesssim 120^\circ\) the following formula can be used to calculate \(\vartheta_\mathrm{3dB}\):
\[\vartheta_\mathrm{3dB}=\frac{31000\times10^{-0.1G_0}}{\varphi_\mathrm{3dB}}\]
