Since you used the term "whip" it tends to imply some physical motion or
vehicle,
vs a "vertical" which implies a stationary location.
And both imply a omni pattern - like a general Access Point -

-=-=-=-

OK, time to clarify...

Wifi (2.4 GHz). outdoor omni vertical (not whip), permanent mount on pole, to
be connected (very short pigtail) to pole-mounted wifi router in client mode.
Max output: 250 mW.

Is it true that the higher the gain the flatter the "donut" shape of the
sensitivity field?

(And yes, my terminology is rudimentary... please forgive.)

why omni on a pole in "client mode" ?

If you are attemtping to connect to a specific Access Point,
this has been discussed here zillions of times,
and there are other questions, clarifications, and solutions available -
other than an omni -
Where are you in relation to the Access Point, how far, line of sight, etc

This requires a little different "thinking" than just putting up a bigger
stick
to talk to a 2m, 220, or 450 repeater -

I'm the one who initially committed than terminological crime so forgive
ME! Where is that big omni gain going to come from if not from the
vertical beamwidth? Start with the isotropic model pictured as a
spherical balloon. Squeeze it however you want to. Nothing about an
antenna can add volume to the model, its just a matter of how you
squeeze it.

That is the only way to get actual gain from a (horizontally)
omnidirectional antenna (excluding any MIMO designs).

Flattening the vertical radiation pastern may have severe drawbacks
especially if the mast is swinging in the wind or some weak (e.g.
indoors) users are close to the base of the mast.

You still don't describe what sort of connection you're trying to make.

I have this Comet antenna mounted on my roof and it works super!
