Here¡¯s the page showing the extraordinary losses in a simulation: ? Up to 950 out of 1000 watts ?dissipated in the resister! ?That¡¯s even worse than 10 DB. ?

Think through what is being said.?
A Loss of only 30% would be somewhere in the range of one dB¡ª-unnoticeable.
But Almost everyone notices losses with these antennas. ?Even on receive!?
The primary reason you have a ¡°quiet antenna¡±, is because losses are so high that it can¡¯t even present your receiver with a strong signal from the normal ionosphere static!
Such lossy and wideband antennas have their place, but I agree with one of the writers , give me a low loss feed line and Antenna ?and I¡¯ll use an auto tuner. ?Last thing I want to add to my Antenna is a dummy load resistor! ? Unless I¡¯m truly forced to.

By the way, a 10 db loss would be represented by a loss of 1 1/2 S units figuring an S unit is 6 S-units as usually measured.
