Due to unwanted, but unavoidable reflections at mast adapter, indexing ring and cable etc. the shown directional patterns deviate somewhat from the theoretical pattern shape (typically less than 1 dB). The H-plane pattern of an ideal half-wave dipole is circular. The half power beamwidth (- 3 dB) of the ideal half-wave dipole is 78°. The reflections in the antennas' direct surrounding increase the gain figure in forward direction (to the right in the above sketch) by +0.5 dB typically (theoretical isotropic gain of a half-wave dipole: 2.15 dBi).

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)
