This is likely to occur only when the object of concern is carrying 
current at the frequency of interest, in this case, 160M. That requires 
that the object be close to resonance (quarter wave for a grounded 
tower, including the loading of what's on top), but the shorter tower 
you're concerned about is NOT close to resonance on 160M, so is not 
likely to be an issue on 160M.  It MIGHT be an issue on 80M if you have 
an 80M vertical nearby.
