Hi, I have designed a space ship to pick my man from Duna. It's build from "space part" and Lander. I really wanted to save space, so I used Communotron HG-55 to communicate with Kerbin and HG-5 to communicate with Landerm, which has Communotron 16-S. HG-5 should be a relay antenna, but I have no signal. Can a Probodobodyne HECS2 operate two antenas? Where is the problem? Thx for answer
