What is your maximum 'lag' compared to the size of
your study area? If the maximum lag is more than
one-half (some people say one-quarter) of the maximum
distance in your area, you will be getting the common
artifact caused by diminishing numbers of pairs.
If it is a real cycle, it may be of such a large
extent that it is irrelevant to your analysis.
