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!
