I have found a good lesser expensive alternative to the large power dissipating attenuators is to use a calibrated power tap. There are numerous diy plans to build a 40db model. With a good 100w or so dummy load on the output of the tap you are all set... AE6PM has published a pdf doc on a 40db power tap... W2AEW video #61 has a good tutorial on power taps.... And you can use your TinySA to calibrate it when you've built one...
those little tiny attenuators are useful too, i use a 1 watt one basically as a 50 ohm termination on the input of my oscilloscope so i can watch the rf envelope from a sampled signal of the transmitter's output
For what its worth, I left a comment on someone's video about a 1kw, 50 ohm dummy load. The video had nothing to do with the topic. So apparently YT analyzes the comments you leave for suggesting videos. Good to know, I guess. Anyway, it looks more or less like the square attenuator only about 2 shoe boxes in size and oil filled. Also, no output since its just a dummy load.

now that i think about it one of those would be a really good quick matching device for a whiskey bottle antenna... lil 1db 1 watt job .. hmmm

Can the device pick up the frequency of 5 kHz? 🎉
No
