You might also consider the total coax length of each option.

You don't say what frequencies you plan to operate. However if 6M and above an extra 75' might introduce significant extra loss-- depending upon type of coax used.

As a general principle, isn't it best to have the single-point ground as
close to the electrical service ground as possible, for minimum
resistance between them?

I want to determine the best location for the cables and coax to enter
my house for my new tower installation. Many of you have extensive
experience in these matters and I would appreciate your thoughts.I
have a Ufer ground at the tower will as well have a cadwelded star
ground system radiating out from the tower.

The coax and control lines are my concern. There is a house perimenter
ground starting outside the shack and going around the outside of the
house directly to the telco and electric service entry point ground
where it is then tied in to the tower star system. The shack in the
house is diagonally opposite the telco and electric utility entry point.

Am I better off bringing the cables into the house via a bulkhead with
suppressors tied in to the perimeter ground

A) right at the telco and electric entry point (relatively close to
the tower) and bring the cables then through the basement or

B) further away ( 75 ft or so diagonally opposite point A in the
house) where the shack is and run/trench the cables outside to that
point.

I thank you in advance for your comments and suggestions.
