That could be true, but for several years my inverted L (86 feet up and 68 feet
out, over 1.5 miles of in-ground radials) is significantly less noisy on
receive than my 270-foot center-fed dipole sloping (intentionally) from 83 feet
to 7 feet.

Unless you like listening to noise you don't use an inverted L on 160
(or 80) for receiving.
