For portable you could buy a Diamond antenna but beware of fakes (https://forums.radioreference.com/threads/how-to-spot-a-fake...) See that you buy one with the right connector (RP?, male/female). I have an srj77 from diamond on my anytone that fits and works fine.

For larger handheld or fixed you could build/buy a yagi antenna that has a higher directionality/gain.

That was one of my first computer programs: compute a 'perfect' Yagi for a given frequency. Of course it will never be perfect because you will use tubes with a non-zero diameter and there will be something to carry the reflectors on and so on but it's amazing how close you can get if you cut and space precisely.
