# Need help understanding the gain on antenna pattern plots

My understanding is that the value of the axis (like -10 / 0 dB) refers to the maximum antenna gain (e.g. 12dbi).

So, if a point on the figure is -5dB, then antenna gain of that point is

12 - 5 = 7 dBi.

Is this correct?

The axes in the figure are in degrees and dB.
