I'm comparing elevation plots of an antenna. They have different
forward gains, this makes it difficult to compare the lobe shape.

Is there a way to equalize the gains to do a comparison?


Example: I have an antenna that is -19dbi and one that is -23dbi.
Can I add 4db of gain to one to make the comparison easier?

I am wondering what type of antenna has -19 or -23 dBi gain. I would
speculate that they are quite omnidirectional, and the patterns wouldn't
be significantly different.

It's tough to get gain that low unintentionally. If they are commercial,
could you please point me at a web site? I'd love to see why they made
these.

but 0dBi would be perfectly omnidirectional by definition. either he is
reading the scale wrong or is looking at f/b ratio instead of gain, or maybe
looking at depth of a null or sidelobes.
