I get the reference to the original meme. I don't understand the EM spectrum component, though.

They wish they were in an antenna and going out as radio waves, but instead they’re in a dummy load and not going anywhere. 50ohm is a common antenna impedance.

Had to go get my radio-tech spouse. His reply "Oh, that's the dumb name for a terminator...."

Apparently "dummy load" isn't what they call them in the USAF

That's my understanding as well. I've seen dummy loads used when testing transmitters at power so that nothing gets too hot. They usually have a big aluminum heat sink.
