Default Whip on portable vs Dipole Gain for 2m or 70cm

Hello,

Would like to compare link budget between
portable-radio with typical small rubber whip antenna and
vehicular-radio with 1/4-wave or 5/8 antenna or vertical dipole on the
roof

Gain difference between vertical ground plane and dipole is about 2dB.

What I'm looking for is the gain difference between

portable whip

It's a NO-NO. Don't call it "antenna".

1/4-wave on car roof

THE standard.

5/8 on car roof

Definitely bad on 2 meters.
Whip is elastic and moves and wiggles and causes additional QSB.

Vertical dipole

Not on a car roof.


Does anybody have more info?
You do. What's your operating frequency range.
Why do you keep it top secret?
