I forgot to say that, depending on the frequency (higher is worse) it’s almost impossible to know what the maximum antenna gain you will find in a full spherical is versus three orthogonal cuts. In my products I’ve seen 7dB difference at 5 GHz of an antenna in a product.
It’s also worth noting that there are _very_ few submittals I’ve seen that include spherical pattern data. The three axis palanr measurements are much more common. Sorry for the list pollution of two posts back to back!

Are 3D antenna gain measurements typically different than 2D with regards to peak gain? If so, what's typical delta, 0.5dB or less?
