RF Power Splitter - How does it work?

So I have a series of videos detailing the performance of USB Software Defined Radios and how they perform against each other. I received some comments and some emails basically saying the same thing - your testing is flawed. So I looked into it, and sure enough my testing was flawed. So I added a new item to the hamfest shopping list, an RF splitter suitable to the task at hand. I went looking for one in the retail market and at $100 minimum I wasn't going to do that. Sure enough the local hamfest had a vendor selling them for $10. You better believe I snapped up a couple of different models. This is the takeaway from getting such a device.

Thanks Steve, I'm a curious cat also and I love to dig into stuff and figure out how it works. Sometimes I confuse myself more but that is all part of the journey.

Oh this gets worse. There is a rabbit hole here I was not expecting. Thanks Lionel!

Do Power Splitters fail?
One may think that since P.S. don't have any active components therefore they wouldn't fail.

[@LifeAtTerminalVelocity]

Like most passive components, they can fail if abused.
