Hmm, how much heat does it take for something to become visible? A high power antenna will get hot, but if it’s a signal type that’s jamming resistant otherwise maybe it can use a normal civilian level of power.
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.
I’m guessing they could be seen easily with FLIR, but of course not every drone or soldier has that.

Emissivity is probably different, and if the shell is thin and plastic, probably closer to ambient temp

A receiver should be totally cold.
