Hi, very new player here, and kind of out of ideas on your mod on my first contract. I need to place a satellite in orbit around Minmus. I tried every combination and 6 of every communications device (RA-2, HG-5 and DTS-M1) but it seems like I miss something - I cant get the needed 5.00M relay antenna rating, probably because I dont even really know what that means. Can you help me out? Thanks! Picture is from the launchpad, but it doesn't change when I orbit Minmus.
