Very similar to, if not exactly like the Comet CHA-250 "vertical dummy load".  These antennas are a good solution if your primary purpose is to convert RF to heat.  Google the Comet, no shortage of comments about it.  The takeaway is that if you have the ability to put up a 25' vertical like this, you can put up a different 25' vertical that actually works.
