I'm guessing they could be seen easily with FLIR, but of course not every drone or soldier has that.

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.

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

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.

A receiver should be totally cold.
