If you're losing connection due to a shaking radio dish, as in the original case, a different shaking radio dish is hardly a compelling solution.

They have grid antennas with a slightly wider beam, or maybe a sector style with 20-30 degrees could be used. I just think it's easier to engineer a workable ship-to-ship stabilized radio solution rather than deal with the ship-to-sat dish which probably has much tighter tolerances.
