Tony, will that 3 dB be noticed by users? Probably, no.
Will it increase power consumption, heat generation, potential for desense if
the antenna is compromised by age/weather/damage, intermod risks, and long-term
maintenance costs? Probably yes, yes, yes, yes, and yes.
Without knowing more
I think not

Try 1/2 of an S-Unit.

There's even more than one standard!

No S-meter involved. A 3 dB increase in signal can make the difference
between unreadable readable.

While most people seem to agree that there is a
standard, almost no receiver is calibrated to the
'standard'. The low

I would halve the power, tell the users that you have doubled the power
and watch the glowing reports of greatly improved performance roll in. :-)
That was the results I got 15 years ago when I tried the experiment.

Actually, it is 1/2 an S unit (6 dB = 1 s unit, if you believe
that sort of thing!)
My experience with an additional 3 dB on the transmit side on UHF is
that you *might* fill in a few holes
That's evil!

This was asked a while back, and the results were made into a web page...
http://www.repeater-builder.com/antenna/3db.html
What would be interesting is to add a few sound files to the above article
showing what a jump from, oh, maybe 6 to 9db quieting, 9 to 12db, and
12 to 15db actually sounds
Pretty close to the mark , maybe add a gain antenna and enjoy the results .

Nope. Not likely.
What would you do?
Buy a better antenna with the money or spend it on any upgrade that
would prove to require at least one less trip to the repeater
3 dB is definitely noticeable on my RXs.

Standards, you gotta love 'em. Everyone should have one. ;-)
