Given how common it is on real-world probes to have a backup low-gain antenna that can be used just like this, what if the option was available, but depended on having an omni antenna active? If your probe is dish-only, then you're SOL - poor design decision. If your omni isn't active or you're out of power - too bad, you turned off the backup and you're SOL. But if there is an active omni, available power, and clear LOS to a command station that has the range to reach the probe normally, then it can be used to reorient the high-gain antenna - just like on real-world craft. No other flight control, because this is a super-low bitrate we're talking about, but just enough to point the dish and regain full connectivity. I'd further suggest that the integrated omni in probe cores wouldn't count for this purpose. If you want a backup system, you pay for it in funds, part count, and power. Thoughts?
