Apparently “dummy load” isn’t what they call them in the USAF

i might be wrong here but i think a dummy load is different from a terminator, they both 50 ohm, but a terminator is more like a connector cap, while a dummy load is designed to dissipate heat and can often take many watts of power over extended time without starting glow

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.
