On the ballon you want on omni (putting a dipole on a ballon is pretty
trivial in any event), on the ground you can have as much directionality
and gain as you find practical.

Given there are quite a few DX/contesting wizards in the bay area with
fairly outrageous rigs it's mostly a question of figuring out what's
link budget you need and planning accordingly.

gmrs is right around 462mhz up at the top of the 70cm band
