I'm a retired RF engineer that has fallen in love with FPV racing drones. With FPV systems, you have video transmitters that can be damaged very easily if they are powered up without some sort of load on them, i.e. an antenna. Many drone pilots remove their antenna for storage and/or travel and have at one time or another powered up their system without re-attaching the antenna. When that happens, damage can and will occur to the unprotected amplifier. In my job we used terminations, or "Dummy Loads" to protect our transmitters while testing or shipping. That's what these terminations due ... when a pilot removes the antenna for whatever reason, they can throw on these small loads and be protected if and when they forget to replace the antenna. It's one very inexpensive insurance policy on your expensive transmission equipment.
