A friend of mine once had a similar problem.  He had several repeaters
(back when they were a new thing) on 6M linked and wanted local
general coverage and beamed coverage to the next link.  He solved the
problem using a omnidirectional (ground plane, colinear, etc.) antenna
coupled to ( and spaced on the tower appropriately) a 15 element yagi.
This created a "Keyhole" pattern and worked quite well.  I don't
remember the exact coupling or spacing but you can probably find out
from a good antenna reference manual.
