this was a qustion from my instractor in college

The assumption may be an error to begin with.
For starters I would say a 5/8 wave antenna may be "more ideal".
If you picture the radiation pattern similar to a balloon with a finite
amount of water (the 'power') , the coverage of the antenna can be
represented by the shape of the containment.
If you press down on the balloon center with your hand then the circle of
coverage will be larger - since we assume the cell towers will be on the
same plane as the antenna, you can see that a flat, circular shape will
cover more map area than a spherical shape would cover. A 5/8 wave antenna
is but one of many types which can exhibit 'gain' by distributing the
pattern in more usable directions.
I suspect the antenna the Instructor is referring to is 5/8 wave, and he
tried to throw you off with the 'Ideal antenna" statement.
