I can't think of a good way to word it - except may to say a pair of rods
closer than 2x is less effective - but say you had a pair of rods 3x (or
2x) apart, and you added a rod BETWEEN the pair (making each rod 1x or
1.5x) between each rod.  I believe that wouldn't reduce effectiveness
(except for your wallet)
