HPBW / vert.

The effective angle of coverage of the antenna in the vertical plane, technically — the angle within which the signal power will be at least 50% of the maximum.

For details about the meaning of this parameter, see "HPBW / hor." higher. Here we note that if the antenna is not tilted, then the middle of the covered sector (that is, the line where the signal is most powerful) runs horizontally. Therefore, if another device to be contacted is above or below the antenna, the latter will have to be tilted for maximum communication efficiency. However, absolutely accurate guidance may be required only when receiving a very weak signal on a narrowly directed antenna — in other cases, hitting the HPBW itself is quite enough.
