Make a tower/pole on the barn high enough that it can see/be seen by all the houses. Put two Nanostations on it. Configure them as Access Points but use different channels (not frequencies). Use Nanostations or Lite Beams on the houses. If you have clear line of site between the barn and each house use 5 ghz radios.
They make and omni antenna that can be used on a rocket or bullet radio but I will not recommend it because they are very susceptible to interference. There is a reason that you see radio/antenna arrays on towers.
