Sorry Bob, but in all sincerity, I gotta ask...
If the *noise* is "noticeable[y] quieter, 1 to 2 S units", wouldn't the
wanted *signal* also be down 1 to 2 S units? Your theory about lobes and
noise has merit, but presumably the signal and noise would be affected
equally. (or could it be that the wanted signal is horizontally
polarized and noise is supposedly mostly vertically polarized?)
Inquiring minds want to know.
