Good question - I haven't seen that 'rule of thumb' before. Since a
tall object (tower, tree, bigger structure of some sort, etc.) offers a 'cone
of protection' and mostly protects objects under it in the COP, I would say
that (with a proper ground system) close proximity is not a negative. Almost
ALL commercial equipment buildings are VERY CLOSE to their towers and many
routinely get lightning strikes with no damage to tower, building or
equipment.
The ROT isn't a bad idea but usually not very practical. If the tower
is that far away, then it's pretty much decoupled from other nearby
structures.
