There is no disputing 1dB is worthwhile in the rare
situation where a signal is hanging right at copy threshold,
but I think someone well-versed with signals, noise, and
statistics would have fun with the idea 1db would suddenly
open a doorway to a room full of extra QSO's.
I think the threshold for that is more like 5 or 10dB.
I barely notice a difference between my omni and 4 square,
and that is a good 5-7db change. As a matter of fact I'm
always amazed what a dipole at 50 feet, virtually always
10-15dB down, can work.
Look at the people who swear by a few elevated radials, or
who love GAP antennas!
