It might be more interesting to discuss something like $/db to get to
closer to optimum. Going from low dipole to a higher one might cost
zero to a couple hundred and gain 3 db at about $10-$100/db.
You will find exactly that analysis here.

Also, several changes of a dB or two add up. Anyone who's ever tried to
make QSOs over a difficult path in a contest can tell you that as little
as 2dB can be the difference between making the QSO and the other
station CQing in your face.. Years ago, our NCCC resident statistician,
N6ZFO, even managed to assign a percentage increase in Sweepstakes
scores to a dB. In my station, I've worked to squeeze every dB out if
that I can -- everything from antenna height to a better feedline to
more accurately reading TX power (I use N8LP's power meter, which allows
me to get right to the limit, whether it's 1.5kW or 5W).
