I decided to move my base to a new planet. And, having a fresh start, I decided to place it as close to the planet’s portal as I could.
I found the portal, built a signal booster, and scanned for the nearest habitable base. It was more than 20 hours away. Now this is quite a densely populated planet, so I found that result a bit hard to believe. So I used the scanner again. This time, it found a base just under 2 hours away. Better, but not great.
So I scanned again. This time, it found a base only six minutes away on foot. About 30 seconds by exocraft. I can actually see the portal from the base site.
So, when you use the signal booster, don’t just accept the first result it gives you. There may be better options.
