The DTV dongle unit? Cheap price. I ordered one. I cannot even begin to explain how hopeless I think it is. In my view, it is beyond understanding how poorly this performs.
Get anything else. Get an old shoebox, draw on it with a sharpie, and pretend you have an analyser. It will be just as useful.
I hope they work reasonably well as I just ordered 6 of them. These are for some techs I work with that just need a basic scanner.
Will compare to my Win Radio system and if they are really bad, just send them back.
If they work as well as an RF explorer , I will be happy.
