[TowerTalk] Tower Base Height & Lightning Umbrella?

We are about to schedule the return of the concrete
truck for the second phase of construction on our new
steel house.

Among other things they will pour the tower base and I
need to finalize my decision as to location.

As you may see in my crude ascii drawing below the grade
slopes away from the house to the proposed main tower
location approximately 20-25 feet from the corner of the
house.

Question:  If the base of the tower is more thoroughly
grounded than the house and is also located 4-6' lower,
and the top of the mast is 40-45 feet taller than the
house, will it

a) provide any appreciable umbrella of lightning protection
due to presenting a far more efficient path for resolution
of potential?

b) Does the relative height of the base matter at all in
the assessment?
