Insisting on omni antennas for those on the fronges of coverage of a given
cluster may actually hurt rather than help. The key is to be able to hear
others accessing the same cluster, which you may not be able to do without
some gain. If the others using the node are mostly within the pattern of
your yagi, collision performance may actually improve.
