Device sold as "dummy load"

Good afternoon. I want to ask you to please inform me about some devices or parts that are sold under the name of "dummy load", on which equipment is used and what is the purpose of its use. Thank you. Attached photo of the piece. [Img] https://cdn.yoreparo.com/uploads/imagen_post/0002/75/c3a17f20e7d96668f2c49aa2ec69c48eab1157ac.jpeg [/img]

I am sorry to say that I did not explain my query well. I fully understand the function of a dummy or phantom load on radio transmitters. The consultation was to know and know if the piece that appears in the photo, also called a dummy load, is for use in RF transmitters or has some very particular use, given the small size of the piece, not larger than that of a TO 3P transistor. On the other hand, in the data published on the page that offers them, it indicates "50 ohms and 250 watts"

With these non-inductive resistors you can perform phantom charging with one or several in parallel to increase the dissipation power or they are also used in dividers / adders Wilkinson
