A number that will reduce interaction substantially is 1/2 wave worth
of philly on the LOWEST frequency in use on top of the tower.

Others may tell you that going all philly except for the last 12 feet
or so to the ground is needed to clear up interaction with any of the
40 antennas, shortened or otherwise.

N4ZR has a particularly telling story about that. If he doesn't pick
up on this thread, you may want to post him direct.

73, Guy.
