Not very practical ides -- sorry.
FOX is a 1U Cubesat, 10cm=4" on a side. Kinda hard to fit 10M dipole
(which would be ~16 ft long, fed in the middle). You can't do it with a
monopole because the 4" box doesn't have enough size to feed a monopole
against. And with a 4" cube (even with deployable panels) we can only
expect a total of a few watts (orbit average) of power.
The laws of physics and engineering are rather unforgiving!
