How portable are you envisioning with said antenna?
As above, a base antenna would obviously be best. SMA to PL259 adaptors and pigtails are a dime a dozen.
For potential emergency deployment in the field, I pack a roll-up J-pole made of ladder line and twenty feet of feedline. It can be put up anywhere and have the range of your HT greatly increased in about two minutes. Using a VX7R, I’ve tested it from the center of my in-laws’ basement (for the ultimate in poor conditions) and was able to hit repeaters that were impossible using a rubber duck antenna.
