Power.
For 2-meters, try ERP of 25+ watts or more. HT's only
work from Mount Everest, Hawaii, South pacific, Mid
atlantic etc. The closer you are to a big city, the
more power you need. Close means a city closer than
500 miles.
For 70cm, try ERP of 50+ watts. (ERP means you
subtract your coax loss and add your antenna gain)
