You've installed the mod without first installing ModuleManager. I know, because I did the same thing. Once you install ModuleManager, you'll find that all stock antennas are Relays, and that all capsules have a small amount of Oxygen and Food.
@ShotgunNinja, I know "requires ModuleManager" is written on the OP, but is it possible to detect MM's presence at startup and issue a warning if it's not present? I've counted at least 3 of us here who have made this mistake, and presumably it's happened to others who don't frequent the forums. That is, if it's even programmatically feasible...
