Rotten based on recovered signal strength. A low efficiency antenna that 
can require a low noise preamp because the typical HF receiver has 
relatively poor sensitivity due to the normal level of atmospheric noise 
on an antenna like a dipole is much greater than the signal or noise 
from the Beverage. The Beverage is superb for LF directivity which can 
often give a greatly improved S/N if the receiver has a low enough noise 
to hear it.
