Have you actually tried one? Mine seems to work.
Define "work." N6BT famously said many years ago that everything "works" by quickly working all continents on a light bulb.
I was ready to put
out radials also, but doesn't seem to be necessary.
The earth is a big resistor. A connection to it does NOT make a transmit antenna work better -- indeed, using earth as a return adds a resistor in series with the antenna that burns TX power, making our signal weaker! Radials serve as both a counterpoise -- a low resistance return for antenna current -- AND to shield the antenna's field from the lossy earth beneath it, also minimizing the loss of TX power.
There's a conceptual discussion of this in slides for a talk I've done at Pacificon, Visalia, and to several large clubs.
