Dave,
"...as good as it possibly can..." is in the eyes of the beholder.
To where do you wish to communicate? (place on the earth, or elsewhere)
When do wish to communicate? (Time of day, season, sunspot cycle, etc.)
These are good questions to answer; then model the antenna at various
heights.
That should help you determine the height to place it. BTW, regardless of
the height chosen, it will be a compromise! But there is no place where it
will be "...as good as it possibly can..."

Subject: Re: [TowerTalk] Are higher HF antenna's really better?
My understanding is a yagi performs as good as it possibly can when it is 1
electrical wavelength above the ground. Any additional height is redundant.
