Isn't there some restrictions on structures that can effect the field-strength
when the structure is near a BC station? I want to remember that if your tower
affect the field-strength distribution of a BC station you have to take measure
not to disturb it.
I am sure, if you have any sizable voltage/current induced by a nearby BC
station you certainly change the radiation pattern from that station.
Just something to be aware of.

When the T-top is resonated into the BC band, be prepared for some very high
base voltages if it's located anywhere near a BC station at the top of the BC
band. The better CIA and VNA devices can be operated in these conditions and
still provide valid measurements.
