Im not very familiar with relay antenna and am having a connection issue to a lander. I have an orbiter lander pair around Vall. The small lander was attached the entire ride but the second i detach it, it lose comms and control. The orbiter has a communotron 88-88 and a RA-2 relay antenna while the lander has a communotron 16. My understanding was that with 88-88 would providing connection to Kerbin the RA-2 relay would be able to communicate with the Lander and give it connection to Kerbin. Do I need a relay on the lander or do I need a relay antenna powerful enough to reach Kerbin on its own?
