Oh right. I supposed unless it’s absolutely cooking a thermal blanket would hide it decently well. You’d need to be careful the radio/microwave frequencies of interest aren’t blocked as well, though.
Edit: If it’s a non-directional transmitter you can just find it pretty easily from it’s transmissions anyway.
Emissivity is probably different, and if the shell is thin and plastic, probably closer to ambient temp

A receiver should be totally cold.
