CommNext is a complete CommNet (KSP connection system) overhaul, inspired by KSP1 dynamics and additional utilities to make it easier to use.
Now connections between vessels need to be in line of sight (so celestial bodies can block the connection). Implementation has been crafted to be optimized, so don't worry about performance, just make sure you have moar sats!
Not every vessel can bounce signal to another one: you'll need relays! In the spirit of KSP1, only dish antennas (RA-2, RA-15, RA-100) are allowed to relay signal. You'll need to setup a relay network in order to bring your missions farther in space.
