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.

I would imagine he is checking for cross polarisation
