That can't be quite right. A gain antenna can be put on the moon but its half power beam width will be limited by libration. If we put a 2.401 GHz dish on the thing we could easily stay inside the HPBW and likely not need much power for a decent signal into a small dish on the earth.
The problem is what to do with the things in the dark when it is truly cold and similarly hot when in the sun. I suggest no battery and nearly as dumb as a rock linear transponder. It probably isn't an earth satellite so it doesn't need much in the way of control. Interesting to say the least.
